Re: 84 GMC straight 6 repower
Yeah I've wanted to do this for quite awhile now, got 2 tractors to get done here then I'm full force on this mad scientist project! Got most of the big parts rounded up, but don't know what to do for a rear axle yet. Ring gear on the 14 bolt is junk and is 4.56 gears if I remember right. The axle in the 1 st gen dodge (dana 60?) is 3.54 but the pinion crapped its pants. From the research I've done a lot of guys use dana 80's when they start cranking these units up sooo, is it worth rebuilding the 1st gen dodge rear end or look for a dana 80 that I can bolt in? I plan to pull the trailer quite a bit so looking for opinions.
