Friend of mine may be selling his longblock from his 97 V6, which I would like to put into my 02. His engine has SSM stage 2 heads and lower intake, as well as a small cam. I would like to put in forged rods/pistons, and use it as a diret swap into mine. What differences are there? Ive thought of the coolant sensor (head vs intake), and the crank (internal vs external balance/2 piece dampener). What other bits?
