RE: Connecting rod lifespan?
Part of the piston not moving at bdc and tdc while the crank rotates is the piston dwell time. It's just from the crank pin moving in an arc while the piston moves in a straight line. The piston moving while the crank doesn't is slack/wear though. Pretty sure you knew that. Just wanted to clarify for anyone else reading that may not. Luckily my rods in question are showing no measurable wear.
Anyhoo, thanks again gents for the replies. I'm still fairly green to itty bitty nitros. I still haven't ASSembled the other Mach 427 or 454 yet. I'm gonna do some whittlin on the 427 sleeve and compare it to the one I just put together when I finally get some time away from work. Not that my subpar driving ability needs more power, but lower temps would be great. We'll see. I may have a new keychain.
