GenVI build


Thought I told you guys about this but don't remember where. I got a BBC off craiglist unassembled but all machine work done and all new parts just put it together. Took it to machine shop to have everything checked out and only couple minor problems had to hone cylinders and an oil plug had to be put in. I got a cam for it (comp HR282) lift is 510in and 520ex. duration is 230in and 236ex 110 lobe separation. Going to use the stock vortech heads until budget allows for something else. compression is 9.1 stock crank, stock rods, keith black hypereutectic pistons, edy 2.0 intake and 750 holley. Using an HEI distributor I have sitting on the shelf from something else. 1 7/8" headman hustler headers. I would like to have one of those airgap intakes for it but they aren't giving those away today so its the 2.0. Getting the adjustable rockers and studs for the heads along with correct springs, then I will find the push rod length.  Not sure if the pan will fit with the cross member of the elky

Sounds like a good combination for torque and power! What's it going in?

I don't know much about the gen6 BBC but they are a good truck motor. Big torque low rpm.
Is it a 454 or 496 ?

going in the Elcamino. this will be motor number 4 it came with a 283 that ran but got a truck motor (454) from a 78 one ton. It spun the bearings right after I got it hooked up. Then I put my motor out of my chevelle in it, but it started missing and then wouldn't run both these motors made it out of the garage and no further, so I now have the Gen VI BB. I may save up and buy a set of the procomp heads I've heard good and bad about them. Its just a  thought.

Got the motor and heads done on this gen 6 454. Put a comp hr282 cam in. lift is 510in. 520ex. duration at .50 is 230in and 236ex. on a 110 lob separation. Using the stock vortek heads for now still have to change oil pan. Got a 4 quart chevy pan so it will fit in the A-body frame, and hook up an electric pump. New block dosent have manual pump provision.

was concerned about the tiny holes in the gasket but come to find out that's ok. I printed some information out of a chevy manual that says no permatex but that aint true either . thought I had everything, but the head bolts didn't have any washers. I got this motor in pieces and so far all I'm missin is the head bolt washers and the balancer bolt.

I'll stab the motor today after work. this is the 4th motor I've had in that elcomino and haven't made it any further than my driveway. The original 283 ran but I know it was tired so I pulled it, was gonna rebuild but then got a deal on the 78 chevy 1 ton. Took motor/trans out put it in the elky and made it to the side of the garage to wash it when oil pressure went away and spun all the bearings. then put my sbc 396 in it and a valve bent when the roller lifter started to come apart. So theres the 283 the 454 then a 396 and now a 454 again, oh and the th400 out of the 1 ton was shot had it rebuilt also. I hope this one works or I'll push it to the curb biggrin

Trying to check pushrod length but something isn't right. First the motor is a gen 6 BBC stock with only a hone stock vortech heads I changed the cam which requires adjustable rockers. The cam is a comp hr282 232-236 duration and 510-520 lift. I have screw in studs and roller tip rockers, full roller rockers were out of my budget.

I bought this motor unassembled so I'm not sure if then pushrods I have are the stockers or if they belong to something else. Does anyone know what themstock push rods are supposed to be.

I would call the cam manufacturer and ask what size they recommend..that way you're assured the proper ones.

thanks guys, I was trying to determine if my tape numbers were the same as the micrometer numbers that 88 was giving me. Guess I should have paid more attention in math class.

It can be tricky for sure. I loved math class in school.

Looking too quick. It looks like your rods are .100 shorter. As ⅝ should be .625 not .725

actually, Comp cams recommends .100 longer push rods for my set up. I bought an adjustable push rod to check for accuracy I just need to put the oil filter on and fill it with oil so I can pump up the lifters.
