69 350 Cam Choice
Hello,
I have a 69 350 Corvette that I bought a couple of years ago which has not been running "right"... so far I've replace the plugs, wires, distributor, rebuilt carburetor, and had the heads refreshed... so now it's time to go deeper and replace the cam which must be worn out...
The car is an L46 car which has been bored 40 over with forged flat top pistons (rated at 10:1 but based on what I've read about the pistons more likely slightly less then that at around 9.8:1)
The car has:
M21 4-speed close ratio trans
4:11 gears in the rear with 255/60/15 tires
186 Heads with 2.02 1.6 valves
Bored 40 over with Flattop pistons
Rochester Q-Jet Carburetor
Choice of Original Cast Iron Manifold or LT1 Clone Aluminum Dual Plane
Hooker side exhaust
I would love to go roller but that's not in the budget so I'll have to stick to hydraulic flat tappet for now. I want as much usable horsepower as possible while still maintaining drive-ability and of course vacuum... what are your suggestions?
... and Thank You in advance for your suggestions.
