Noticed in Leo's book that slipper pistons cause cracking issues in 292's due to the local loads of the piston on the cylinder walls. I think I've figured out a way to drop a 292 crank into a 250 using 5.7 rods, but the off the shelf pistons are slipper type. Can I expect the same issue, or even worse due to the rod angle?

Just for amusement these pistons would also allow 250 crank with 6" rods, and stil be able to deck the block....
