My rods are Crower steel and longer than stock - 7.263". This should make clearances tighter to the cam. I have a cam with the cast in clearances (a 292 not a 250 cam) and have at least .060 to the cam. The only clearancing I had to do was on the oil pump suction pipe boss, which would be a factor no matter the rod length.

I also recommend getting custom pistons and ordering your rods to fit.

I paid 1100 for my crowers. But, I think you are going to have fun making the GRP's fit. Good luck!
