well heres another guy planning to fit an eagle 383 internally balenced set (no forgings for me though)

Sixty6, do you have 6" rods or the 5.7"?

is this clearance issue with the cam shaft a common prob? not sure id like to start grinding rods that have been fully internally balenced. luckiyl i wont be buying untill this summer so i still have time to make allowences
