Chevy 350 rebuild opinions

[rich weyand]

From Comp's Camquest software. Like I said, dyno simulators aren't real accurate, but they do allow you to compare and contrast different cams. That is, assuming the errors cancel out. Like, if it is too optimistic on head flow rates, that should be the same for both cams. So you can still compare one to the other.

The numbers are for a stock 350 crate engine like the 350/260hp $1500engine. That's with a dual-plane high-flow manifold, 4bbl carb at 600 cfm, 8.5:1 compression, and long-tube headers with mufflers but no cats. If you assume the CR is more like 8:1, it's still over 410 lbft at 2500 rpm.

I think faster ramps were more of a problem when it was by guess and by golly. With computer aided design, the computer can tailor the ramp much more tightly.
