Chiphead, These rods should have lockwashers. I'm pretty sure that my rod failure was due to a lockwasher breaking allowing the small end to open up the thickness of the lockwasher. I talked with Leo Santuci, the 292 turbo guru. He used to race 216's, 235's and 261's and says he believes my engine woes is a freak occurance. He never had a rod or crank failure, never replaced the lockwashers or bolts with new ones. He is allways trying to convince me to put a turbo or at least nitrous on my 235, so he believes the 235 will take it. Now if I can just find out what to torque the pinch bolts to.
