Fuck, I forgot you were collecting reactions. Sorry about that.
I don't see why a magnetic drain plug full of crap means anything? Bisi's had some fast Hondas for the exact reason Tim Lynch is killing everyone in 10.5 Outlaw - and I quote, "lots and lots of test and tune." Bisi picks a platform and stays with it for YEARS longer than most people own a car. Further, a block's webbings get fucked up when sleeving and sometimes they don't align bore correctly, or they do align bore but the block wants to flex under power. Take the engine apart, see what needs to be fixed, put it back together again. Same procedure anyone with a fast as shit car goes through.
