Hello guys. I did some mods to my 81 Corvette, and it seems to run alot better, as I expected it would.
Originally it had a 350 w/computer controlled Q-jet and Dist. Pollution eqiupment, all stock. Has a 2.87 posi and single exhaust out the back duals.
27 inch tires and 7.8 cr, and a super small cam(stock) not sure of specs but I think about .390 lift.
Well, I don't like to waste tons of money, but I like to match parts as best I can.
I removed the smog stuff, and carb and dist. I installed a Regular Q-jet and a performer intake. I installed a new HEI w curve kit. I put headers on and TRUE duals out the back. It has a TH-350 trans, and now the rear gears are 3.73.
The cam I picked was comp Cams #12-231-2 which is 206/214 dur and 432/453 lift 111lc.
The car was a true dog before, but seems to get up and go (for what it is).
My question is now, If I were to get rid of the old 76 cc heads and upgrade to something like a Vortc or sportsman II or even an older casting with acc. bolt holes that are 64cc, would I notice much more of a difference, or it that a waste of cash. The issue with putting the heads on is no big deal to me, can do it in about 4 hours, but will I really get much more out of it with the cr being raise a little? Let me know. Thanks.
