Just got back from my engine builder, Keith Craft in Arkansas, and very pleased. The little 331 made 440 torque & 521 hp @ 7100 rpm and still wanted more. The motor wants more compression and bigger cam but this is just fine for now. If I get serious down the road and want another 100 hp I know what to do.
302 R-block
Neutral balanced rotating assembly
10.5 compression
solid roller
Yates style C302 heads, titainium valves, T&D rockers
Roush C302 intake, 750
Keith runs a first class show and these boys take their Ford motors very seriously.
