Like I already posted earlier...I knew it was a 340, seen all those pistons before and as I said... you can tell by how close the 8553 felpro head gasket is to the bore. 4.180 -.4.07=.110...and that's what it looks like.
Yes! Sorry, I meant to scroll up to look at your name to give you credit. I'm probably going to rebuild it with forged components and get rid of the blower. Wouldn't an 871 chew up these cheaper pistons?
