426 inch+ small blocks

Thinking more about high stroke motors, the pistons rock more at TDC with higher strokes. Plus using a 4 inch stroke in a SBM..any SB.. means you have to use a shorter piston, which will rock in its bore even more so.

Maybe the engine won't break but the ring seal is not going to last as long as the short stroke/long skirt pistons and its going to burn more oil.

But hey, most people now baby the heck out of their rides, its more for show than go. So many are getting away with 4 inch strokes, I guess. Doing 360's in the rain/snow is a thing of the distance past, lol
