My 1989 Chevy Pick up -> Engine swap EFI to Carb


Here are some Photos of what I have been up to Lately . I removed the 5.7 Engine out of my 1989 Chevy pick up . It was smoking a Lot on start up-s and the EFI was not working right . So I swapped it out for the 305 Test engine . And I am converting it to a Carburetor Set up with a Manual Fuel Pump . Also I am trying to do this as cheap as I can . I spent more then I should have on Cars this Summer . Sound not to hard Right ? Take a Look and see hmm


As For My Truck ? Lot's of Changes have to be made . I need to cut the Fuel Line at the Frame right before the EFI Filter . Then Run a New Section of 3/8" Line over to the Passenger side to the Manual Fuel Pump that I will be using . You can Leave the old EFI Pump in the Tank with no power running to it after I remove the Relay / Wiring . And the Manual Pump can suck Fuel through that Pump and in tank Filter with Little effort . I will have to make some Mods to the Heater Hose hook up's . Brake Vacuum Line . And remove Lots of un Needed EFI Lines Feed and Return that Mount to the Fire wall and the Computer ECM and Wiring . For Now I will run my Log Exhaust Manifolds . But Late on I may go with a Set of Headers . Also I have to make sure what ever Carburetor I run . That all the Linkage hooks up and is set right for my Trans TV Cable .

If my in tank Fuel Pump was in Fact good . I could hook it Up with a Regulator and use it with the Carburetor Set up . I have the parts to plum it ? I just want to walk away from that junk and make this truck a better running Trouble Free ride . That 5.7 in it's early days when it was fresh tuned ran ok . But never strong Like say a 350 4bbl Pick up of the 70's . So I really do think the 305 will push this Truck better .

Here is some more of what I will be up against . Ya there is Lot's of Room to work under that Hood . But working on Pick Up Trucks Suck because they Mount them engines down so Low and you play Hell trying to unbolt everything . I would much rather change Two Car Engines back to back then one Pick up Truck Engine Image

I stripped off the Test Parts from the 305 it Ready to be Dropped into the Truck .


Image

Image

Here is that Re-Man 5.7 Water pump . I will need to use the Factory type to work correctly with my Pulleys and Brackets .

Image


You would think this would be a walk in the park doing this Engine Swap ? No I found more problems that I will encounter . Yes the Factory Mounted that Engine more to the Passenger side ? Not sure what their reasoning was for doing that . But I have seen Lots of Fords just Like that . Here is another Problem I am going to have . The Gas Tank is mounted right were the Lt Side Exhaust Pipe and Muffler should normally be Mounted . What I will have to do is snake it to the Center next to the Rt Side muffler just above my Drive-shaft . But it would be best to run Glass Packs for a Better fit and more clearance . And I really don't want that added Noise . I took another Look at them Factory Log Exhaust Manifolds . Man are they thin and restrictive . I am still thinking about other options that I may have to save money . I have some Ram Horn manifolds . But then I will have to do the Longer Spark Plug wires going under the Exhaust Manifold thing . I never much Liked that . And I have a Set of Ported 1978 Z/28 Log Manifolds I might get by using them with a 1977-80 Truck Y-Pipe .

I don't know it might be best to throw in the towel and Junk this Truck . It's not in such good shape and this swap is starting to be costly . I don't Like to give up and walk away . So I am going to just pull out that Engine and all of the parts I won't be needing . And just start from there . I will make it work .

It was a Bad day for Me and My wife . Because I had that Junk Truck Parked in the Back next to the Garage . She damaged Her car Parking it . I felt Like crap about that and did some of the Best Body Work I have ever done this Morning trying to get her car back to how it was . After that Happened I wanted to Junk all of my Junk Project Cars and Truck . I am a hard head with this Car and Truck stuff and have brought back many Cars and Trucks that others would have just sent to the Bone Yard .

I never Much Liked this Heavy Creeper with the Big Wheels . But Looks Like I will be spending some Hours with it on this Build :gimmefive2

Ok I think I came up with an Idea that will work . I am going to use my Exhaust Manifold off my 1978 Z/28 with 1977 K10 Truck Exhaust Pipes . I will have to modify the Left Pipe to go up and center more and Run Glass Packs as Far back as I can with Turn Downs :gimmefive2

Here is another Problem that I may run into . With that Engine Mounted so Far to the Rt side . The Exhaust Manifold is near a Frame Bracket . And that manifold is curved for more clearance near the bracket . The Exhaust manifold off my Z/28 Rt side is Flat and might just Clear that bracket ? I might have to do some Tango Mods to make it work . I think I will test fit it on the 5.7 before I take it out . Also there is a Bracket that is not used . That is most Likely for an air pump set up . That is part of the Main Bracket that Holds the PS A/C and Alternator . I will need to trim that part of the bracket off to make room for my Manual Fuel Pump .


Image


Yes to many wires now :laugh2 once I get that Engine out . I will open up the Main Wiring harness and remove all of the ECM wires that will no longer be needed . I already removed the Cruise control that was not working .

Today after cashing my Pay check . I stop into O'Reilly Auto and ordered them Exhaust Pipes and a Fuel Pump made for a 1972 Corvette said with Holley Carb . The Photo of that pump showed it with the suction port going to the Back . That will work out better with how I plan to run the Fuel Line from the Tank . The Fuel Pump and the two Pipes set me back about $100.00 with the tax .

Now when I got home I had to see if that Z/28 Exhaust manifold would in fact fit on the Rt Side . It did and at the nearest contact area it has 1/4" of clearance and exited in a good spot . I will Clean them up with a Hand Grinder The Factory EFI Manifolds on the #1 and #2 Ports are very restrictive . The 1978 Z/28 Manifold are not that much better for performance . I almost trashed them not Long ago . I remember that car ran a Lot Better with Headers . But it had a Well Ported 350 too .


Here is the Factory Manifold on the Rt Side .

Image


And here are the two Rt Side manifolds next to each other . The 1978 Manifold has the Casting Lines on it . I want to smooth it out some before I mount it up .

Image

And the two 1978 manifolds .

Image

and here is how the Rt side 1978 manifold fits . Not Bad I need to remove that Heat riser Shaft and plug it up .

Image

Image

Image

Here is a Photo of the restrictive Factory manifold on the Front ports .

Image

And next to the Older Manifold .

at this point I am just trying to get my truck back running and not spend much more . I would have Liked a Set of Shorty Headers . But I am going to make the most out of the Log manifolds that I have . I Picked up them Pipes and Fuel Pump I ordered today . But then I had to go to a Family Birthday party . So I took a Break from working today . Here are some Photos of what I have to work with . 1977 Chevy Pick up Dual Exhaust Pipes . I will need to trim off the Lip on that one Pipe so it Seals correctly on the Heat Riser Flange that I have to use because of how that Manifold is made . And I will need to cut that Pipe and Turn it upward and use a Pipe adapter to but it back together . The other Pipe should be fine with a section of straight pipe . Then I will go with a Set of Glass packs in the Center above the Drive Line . I did Look at how the Engine is mounted . The Way the frame is made . It would be very tricky to center that Engine . You would have to make some frame tabs . And re-Drill the Trans mounting as well . It could be done . But I think I will be ok with the set up that I have . You can see on my Corvette Fuel Pump were the inlet Line goes . That should work out well too . It has been really Hot out here . But tomorrow I hope to have the Old Engine out .

It's out :getting tired But I played Hell getting that Front accessory Bracket off the Front of the Block . I pulled that Engine with the Hood on and Radiator still in Place :cool grin

It Never fails there's always just one more ground wire :searching2

I started getting some of My Engine Set up work done / Bull work done with Lots of Power Tools . My Friend Let me try out his air saw . For cutting Exhaust Pipe Like I needed to trim that Pipe it worked good . But it could not cut that Air Pump Ear off that Front Engine accessory Bracket . I had to use the sawzall for that . Then I smoothed out the Shape edges on My Exhaust manifolds . I am :boredom and Now I have to go to work .

I installed My 305 Hot Rod Engine today biggrin I had to drill a Hole in the Front of the Rt cylinder head for my Accessory Mounting Plate . Bad thing is that hole goes into a water passage . I think it will be ok . I used Indian Head sealant one the threads of the stud . all the Brackets bolted right back one but one that went off the A/C compressor to the TBI intake . My 4bbl intake didn't have a Hole on that side for it .


Some ECM wiring that I will no Longer be Needing .

I also notice you use Indian Head Shelac. Man that stuff allmost makes and indestuctable seal.. Thx for sharing, cant wait for next episode. Very interesting,wish I was your neighbor LOL

Mokanracer I really do wish I lived next to you . We would have a ball funning with cars and hanging out . My Camera was a Service award from my Job a Few years back . It's a Canon Power Shot A590IS . I remember seeing them on line for about $160.00 . I think it make really good Videos as well . I would only buy Canon Camera's after having good Luck with this one . At first I was worried with it having only two AA batteries but it does not wear them down quickly Like most Camera's do . As for my hot rod fund ? The Money has always held me back the most from going with a more radical Performance Car . Seem Like I am the only one in the Family with a Job . The way I have to pay out for things . And what Little is Left over goes in my cars



It's always harder when you have to mix match parts / make it work all in the effort to save money . To fix this truck so it would run well and be stock would cost way to much . I most Likely won't keep it more then two more years . But I have always wanted to see how it would really run with a mild carburetor-ed Engine in it . The stock 5.7 never ran full out Like I think it should have . I know G.M used Low Performance Heads on them 5.7 TBI Engines . But it still should have pulled better . But It was easy on gas for a 5.7 . I guess the main thing I am trying to do is get this Joker running on a Low amount of cash . Every Time I go to the auto store it's at Least another $40.00 Bucks ? And I am sure I am driven them Parts Guys nuts with all the odd parts that I ask for Ha-Ha one guy ask me if he can test out my truck when it's all done Ha-Ha .

Here is the carburetor I am going to use . It was originally on a 1985 Chevy Tow Truck with a 454 . But it's a non-Computer carb . I rebuilt it a time back with a few mods for a 350 I rebuilt . But the choke adjustment was pinned and riveted . So Last night I drilled out the rivets and re-installed the choke Plate and linkage . This carb should work the best with all my cable hook up-s . I also found this dusty but never used Delco HEI Dist Cap that I will install . And some pluming for my Heater hose to intake hook up . I found these pipes that should work out . I would much rather have brass but this will do and save on my wallet .

Oh I like those Quadrajets. Thats what I had on my 1967 Camaro. But that stinking car was a factory hot rod. Would run 11,s with just a 30/30 duntov and springs. Later on, I started twisting the rotor conductor off the rotor,if ya can believe that. Cant wait to hear and see your truck running, hope you take some vid shots.

Today I got a Later start on my Truck Engine Swap . I started out Flipping my Right Side Valve cover . I needed to do this so my Carb PCV Vac Line would Line up better to the PCV Valve . Then I pluming my Heater hose .Stock on the 5.7 it went to the Rear coolant Port . But my Holley intake only has the front coolant port prevision . It Should work just as well . I Filled up my Block with Coolant . I do this on all the Cars and Trucks I work on . No air pockets and no over Heating on first start up-s . Then I jack the Truck back up and jumped back under there . I hooked up my torque converter . I wanted to check that soon to make sure My 168 Tooth Flex Plate was a go with the 700-R4 Trans . Then I bolted up and Wired my Starter . Next I removed all the Factory EFI Fuel Lines . I cut the 3/8" Feed Line right in-front of the Filter . That's were I will be splicing in my new fuel Line . I test fit my 2 1/4' Dual Exhaust Pipes . I have to say for the most part I was pleased in how they fit . I will have to do a Bit of cutting and bending . But they will be a go . Then I let the Truck back down and Bolted on the 750 Q-Jet . The Linkage was way off . So I had to move the Bracket up one hole . Then I installed my Spark Plugs and Wires . I still need to tie them down better with some after market holders . Next I Installed my fan shroud and upper Radiator Hose and topped off the System .

The work that still needs to be done is . Install the Fuel Line and complete Exhaust System . Fab and Install Vac Line for Power Brake Booster . Install 12 Volt Go wire to HEI re-Check all Fluids bolt on air cleaner .

Even tho this Engine is smaller . I do think it will Perform well with the few Mods that were made to it . It's COOL Looking under the Hood now . It has that Late 70's Look going on now biggrin

I am sure I could Finish it Tomorrow if I had to . But The Exhaust work will be a Bit Tricky . And I want to bend that Fuel Line just right . So it's best I go easy when I do that work .

Ain't that the truth Ha-Ha . All the Time that I have worked on My Truck I was just a few feet away from My Monte Carlo . And Yes My thoughts are I should be working on it . Today about 10.30 A.M I heard a voice that I knew calling My name from out Side My Bedroom Window . It was My dad out Side with the Hood open on My Truck biggrin He stopped by to say Hi smile He said it Looks good and will be Running soon . And he said I should paint it once it's up and running again .

that little truck is pretty straight looking Tango! I think a nice metallic silver with some torque thrust ll's and a little drop would look good but i know you want something practical specially when you put a load on the back. either way I dont think it's a bad looking truck.

I am on Vacation this week so I started working on My Truck at about 3.30 P.M . First I started out by running My new 3/8" Fuel Line . I cut the old EFI Fuel Filter off and spliced in the New Line from there to the new Manual Fuel Pump . It wasn't to bad of a job . Then I used My mighty Vac to pull some Gas through the Line before hooking it up to the manual Fuel Pump . I am running a In carb Fuel Filter . Then Yes I had to see if it would Fire up . I had open Exhaust Manifolds so I did not run it Long . I carefully marked that Distributor before removing it . So the Timing should be right at 12 BTDC Like it was on the Test Stand .

It started right up . Then I shut it off and checked how it starts again

Ok I could not stop at that alone so I kept on working . I had to find a way to tweak a Few bends into my 1977 Chevy Exhaust Pipes ? I came up with this Idea that worked so-so . I drilled a 3/8" hole and bolted a chain to that in this old Laundry Pole I have in the Back Yard . I have never used it so may as well start now . You want to wrap an old Heater Hose around that chain before you place it around the Pipe you want to bend . And you have to go easy you can only bend them pipe a Little bit before you start kinking them .


ei87xk.jpg


These Chop Saws save a Lot of Time and effort when Cutting Exhaust Pipes . I bought this on Cheap at one of them Home Improvement Stores . Wear a Mask and Eye Protection when using one of these .


2ef5c81.jpg


Now this Exhaust System was Very Tricky to make up . I have done this stuff for a Long Time I am sure that came into Play on this Job . I had to hang the Left Side Pipe on a angle and just above My Drive Shaft . I have to say I have had other cars that the Exhaust was even closer to the Drive Shaft then this was after I was finished .

I could not wait to hear how it would sound with that 2 1/4" System and them Cherry Bombs ? I was hoping it would not be to Loud ?

Next I checked out a Few Air Cleaner Housings for Fit . The Factory TBI Housing Fit well . I had to Find a Longer Threaded Rod so it would work with My Q-Jet .  Hey that Tops upside-down ? biggrin


e8qyk6.jpg


The first time I took it on a Road Test it ran good . I could Tell the 700R-4 Trans TV Cable was not right . And My engine temp was a bit on the Hot side at around 210 degs . But even the factory 350 would stay at about 210degs even with the new radiator . Once Thermostat opened the temp stayed at 200degs . I went back home to tighten up that trans cable .

While I was at it and had the air Cleaner off . I Loosened up a Bit on My Q-Jet sec Spring . Then I took it out again .





This Time I was going down a Main Road and Tested out the Passing Gear . Look in the Left Lane . It was a 1968-69 GTO I tried to get him to run my Truck but he was Turning off the road . He only revved it up a Bit as I passed by  biggrin

In the search for just a bit more Throttle response and Power . I took the Cap off my Distributor and installed a Lighter set of Advance Springs and checked my timing again . I also found the slightest Fuel Leak at my Line to Carb that I snugged up and fixed . This 305 runs real strong . If I had shorter Rear Tires and manually Shifted the 700R-4 . I think it could run High 15's .

I took it out for a Test Ride . It was still 90Degs out with the sun down . The Throttle response was better and it seemed to be a bit more snappy .

Thanks Bud to me it's so much Nicer to be able to open up the Hood now and make changes to the Engine . It runs way better then that Computer telling it what it should do 5.7L
