not sure if itll be a 500,i think the 500 turned to a 472 in 77 or something, 425's are common in the late 70's too,im hoping for you itll be a 500
,not sure on the trans,but my thery is if you have no traction you cant break anything,its whrn you start putting bigger tires on ect. that you have to worrie...
