Past 8000 where you need over lap to do anything your just going to end up overscavaging. I think 4340 or a 6061 alloy would be the best bet on this engine. Piston speed doesnt even reach 3600 until around 7800 rpms...



Once you start making high HP/TQ on a square engine, recip weight becomes a factor. A big enough of a factor that it could be what holds the crank together since it's now the weak link in the shortblock.
