So a while back I had my buddy rebuild the engine in my 77 chevy short box 4x4 with a 4 speed trannyWhen we tore it apart we realized it was bored 65 over and needed a new camThe only one we had was a big RV cam with over 500 liftOnly mods were edelbrock intake and carb and headers and bored. 65 over Truck didn't run near as hard as it did with stock cam but sounded nasty and turned some crazy rpm(Little scary with stock bottom end and stock heads) Ran good in that 4 speed truck thoRecently I sold the motor to a friend with an 86 4x4 with a huge lift and 44 in tires Running a stock turbo 400 transwhen we put the motor in the damn truck will hardly move at all!!Thinking that the cam won't make power until about 3000 rpm and with that auto tranny it won't even rev up to that till or 3 miles down the road lolShould we put on some ported vortec 350 heads and a 3000 stall converter? Or try to find a factory cam
So this motor has a bore of 4.065?Save your friend some cash and put in a smaller cam.
By all means put the stock cam back in. Without the supporting equipment that cam will not work well in that motor.

Newb asks a question and never returns...Why am I feeling like a girl waiting for her latest crush to call?Oh the new meds aren't reacting well with the old meds.
Hi there, I would spear that cam and use a 224/230* in place with a 2400 stally. 100lb springs also. Do it easy and make it last. Good luck..
