hell, 6m the bottom end.

on this topic, i have been lookin but have not seen a reasonably priced 7m bottem end for the build. but on a side not my 84 crank was scratched and i will be buying an 82 crank and block soon.
as for the pistons, they are slightly scratched under the rings, but the cylinders on the block seem to be fine...

a big factor will be the condition of this 82 block crank and pistons.

has any one ever milled 7m pistons to fit a 5m block??? seeing as 5m pistons are discontinued???

i have not heard of anyone milling the pistons, but i dont see why it couldnt be done unless the compression height wont permit (material amount). best thing to do would be to measure a set of 7m pistons. im sure turbo pistons would be enough to clear 5m valves, but your CR would be low enough to run on cat piss....great for turbo. some boat motor builders will mill pistons to fit so check your marine builder shops.

sucks that your crank was jacked...getting the crank recon'd shouldnt be a huge hassle unless its just majorly boned..
