That's why I have half a notion to go ahead and built a 4.50 stroke 3" main bottom end using either a real nice 66 389 block that I have or a real beefy early 67 400 block. I wish Jim Zeek had made more passes with his car this year just to see how the block would have faired. I would try to keep the rpms under 6500. Makes my think... Are there many 9 second range 4.50 stroke 3" main motors out there?
