Cam Size

how do you determine the right cam versus the right carbureator for a 350 chevy engine. I want a little more power that the standard 350 but not overpowered.

There's a bunch of stuff that you have to take into account here ... tire size, axle ratio, vehicle weight, desired powerband, exhaust, and intake all figure into the equation.

What kind of car, and what style of driving?

I replaced the engine on my Caprice less than a month ago. The new engine has a Howards 180315-10 grind cam in it, that seems to be good for the application. This cam has a 110 degree LSA, 116 degree intake centerline, .465/.470" lift and 209 intake 215 exhaust duration @ .050". Stock intake w/ 4bbl E4ME carb, stock style exhaust manifolds with dual exhaust, 3600 lb car with 3:08:1 axle ratio and 28" diameter tires. So far, I am not upset with its performance at all.

Thanks that is a lot to consider. I would be putting it in a 1970 Chevy CST-10 truck, with a 350 4 bolt main with a set of double hump heads 2.02/1.60 with either a 600/650 carburetor, intake to be determined, 235/15 tires, everything else would be standard.
