Questions on Lsa block
HKE built a 4.125" x 4.250" (454ci) LS7 years ago, strictly NA since the piston ends up being really short. They were custom too, not an off the shelf part.
Wow i didn't think that would be safe with that block.......How deep is the cylinder on that block ??
I might be buying a Ls7 block next week and they have a 5.800 inch deep cylinder and was thinking of going to a 4.125 stroke crank.....but if 4.250 is safe then i might do that..

Putting a 4.250" crank in a standard deck block isn't a simple task. You're going to have to use custom pistons as no one to my knowledge makes a shelf piston for this yet. You're going to have to clearance the bottom of the cylinders for the rod bolts and you're most likely going to have to use a smaller base circle cam.
