alright so the bottom end of the 22r is better and the top end of the 20r is better. the 2 together make it bullet proof. alright. hehe. im leaving here in a second to go check out this ford taurus wagon, hehe.

the only difference is the 22R has a larger bore piston = more displacement
you could bore the 20R block .180 but

the crank and rods are all the same, just the size of the piston is different
