m20s and m50s are very close in design, close enough that i (like many others) am using a m50/52 crank in my performance m20 build, 328/528 m52 crank with 325E rods on 325I pistons gains me 9mm longer stroke on the stock bore for a 2.8 m20
hey jon if ya want i may be able to scrape up another 2.8 crank rods and pistons (can't remember cr) if you want some more displacement for your build, they should drop right into your block
all america wants is cold beer warm cat and a place to take a poop with a door on it
