427: Gen 3 vs. Gen 4 power difference? I'd like to get opinions on just what the power difference would be building a mild-moderate street 427 on a Gen 3 versus a Gen 4 platform. The car may get FI later, so the compression and cam are lower than normal. Let's assume the following:
427, about 10:1 compression, cam about a 230, shift at 6200 or so
Gen 3: AFR 225 heads, ported FAST 90/90
Gen 4: LS7 heads and intake
What is the likely difference in their power output and curves, given the cam, etc. above?
