'76 sbc build , need more head advice
The engine that is in my car is 70,000 mile 1976 4 bolt sbc out of a truck,487 heads.I put a new RV cam, oil pump,stock timing set,Edelbrock manifold & carb.It is the one with 2 cylinders down.My 74 Vet had 3:08 and it was way quicker and had nothing done to it.3:08 vs 2:73 aren't that far apart are they?I just don't think this motor has the balls it should.
My friends motor that I'm thinking of using is the 10:1 sbc with the big cam.I'm wondering weither to use my RV cam or something else in it.I want mpg not tire burning torque.
I guess what I have to decide now is if to change the motor or not.I'm keeping my th350. How much of a lower gear can I use without hurting mpg?Using a axle calculator ,car doing 2000rpm ,car is 60 mph.
