Right now my current plans are getting either the Sealed Power 677P or the Hypereutectic pistons of the same. I will be boring the engine .030" over and putting in either Crane Cams 753901 or 750501 (can't decide, since I'm not stroking the engine, what cam is good for me?) I hear good/bad things of the Hypereutectic pistons, saying they are stronger, yet more brittle to higher performance. Which should I use to rebuild the engine, Hypereutectic or the normal cast? Thanks!
PM Mudlover to ask about the crank
