OK, 302 now we're talking. So we have the 4 inch bore. My friends that have 347s love them. Is the rod angle really that bad? Doesn't Joe run a 347?

CI Rod Length Stroke Ratio
302 5.090 3.000 1.696:1
331 5.400 3.250 1.662:1
347 5.400 3.400 1.588:1
Beside the ratio it also moves the wrist pin up into the oil rings. With how much I drive my car I would prefer a 331 if I stroke it. My first option would be to stay with the 302 and just port the heads and install a smaller blower pulley.
