speaking of which, what's your opinion of quick break in procedure before running it all-out aside from the obvious cam break in and oil change...

thanks

no the 454 two bolt main will hold more power than you think i know have built many468 496 and have seen them do just fine just say you want one the big block bottom end will take alot .the insurance is building the engine right .not two more holes in the main web .you will have a hard time getting the caps to move around if the caps set in the block good. two more bolts for the power you are putting thru it less you are dumping alot of Nos???? if so stud it. break in as alot with how it hone and how it is built the rings should set in soon if tq plated and plateau honed .the valve springs i worry more about. so they are broke in right
