excaliber The motors in the GT-40 where pretty much stock out of the crates. They there blue printed and the cams where changed but I think that was about it. Jim Holden is a GT expert. He could fill in the answers for your questions. The nascar crank had wider journals for the wider rods they where running. High rpm was causing bearing failures. Wider spread out the pressure of the rod on the crank surface and gave more oiling surface for the bearing to ride on. Compression was 12.5. I am sure some of the others can fill in the rest.
