Advice needed on used crate engine...part II

your '73 core... if it's standard bore and does not need machining you can use these pistons, just put in new rings.

in other words use this rotating assembly in the '73 block.
save the roller block for your stroker build....

Both blocks are standard bore. This is an interesting idea. Nothing is getting bored until the stroker is built.

i know for a temp motor i wouldn't have pulled the heads or anything like that..

Felpro gasket set comes with head gaskets, so I figured it wouldn't hurt to pull them and find out what things look like.
