so tomorrow i will be pulling the engine and trans, i just bought a nice comp cam 572 lift cam, scorpion 1.6 roller rockers, .600 lift springs, retainers, and keepers, new hardened push rods and guide plates, i have a rear main seal spewwing out oil so i thought why not pull the engine and put all new items in it, anyway what should i expect out of the computer when i fire her up? its gonna play hell trying to tame that cam, anyone know of a good tune shop around detroit mi?

 

What year, carb or FI?

 

What in the hell are you putting that cam in?

 

Sorry lol 91 tpi just got the crank back in with new bearings, old ones were all copper, I do have a question about some scorpion 1.6 roller rockers I bought, I put them on just as a test ffit, and the bottoms of them are hitting the head were the studs are mounted do I need longer push rods?

 

That combo is so mismatched the engine probably won't even run. Not to mention, your cam will have .609" gross lift with the 1.6 rockers, which exceeds what your springs and retainers are rated for, AND the fact that your heads won't even come close to accepting that much lift. And that's totally overlooking the fact it's a stock TPI (305 or 350, doesn't matter).

Bottom line is that cam isn't even within the realm of reality.

This is the absolute largest roller cam I would run with that setup:

whats the problem with it exactly? cam to big? duration at .050 is only like 260 or so, i dont see the issue

 

are the 1.6 rockers the problem?

 

Only 260 @ .050"? 230 ADVERTISED duration is generally where you start sacrificing driveability. What cam did you buy? What type is it?

 

this is the cam i have

so running the 1.5 rockers and milling my valve guides a bit i should be in ok shape? is there anything i can do to make this cam work?
