There are even shelf/stocking pistons for 572, both hemi and wedge with normal street compression ratios.

Thanks for the reply.
Lower piston speed w/the .25 shorter stroke.
Regarding the pistons being readily available, the bore of my planned 541 is the same 4.50 as a 572, so unless the stroke changes the piston, which I could see the 572 maybe having shorter pistons or the rings in a different place, but maybe not? the pistons should be the same.
