Does any place make forged 5.3L pistons? (w/o having to custom order) Or does anyone know what a 5.3 block can be safely bored out to? Can you use the 5.7 pistons and not have to worry about too thin of a cylinder wall for 800-900hp at crank?

They dont have to be dished cause the factory one is already low enough compression w/ 317 heads.

Probably the wrong section.... but its for my Turbo build so ?? My car broke and even though its still on the trailer and covered w/ snow im guessing its a rod thats knocking.


Id search the classifieds for pistons but that is so messed up

Wiseco makes a set that would work pretty good with your 317 heads. The iron block can go to a 5.7 bore size no problem too.
