Group,
Has anyone done this? I know I will have to get a different adapter to mate the 300 to the GM TH350 auto, but what about the driveshafts? Will I have to deal with changing the length? What else?
I am doing this not because the Dana 20 is bad or weak, but because the 300 has a 2.62:1 low range, and I can probably do this for less $ than going to teralow gears. I can go to a twin stick as well.
Thanks,
RR
Bill,
I am not sure as well. It is a 76 CJ-7 though, and think it was, but I could be wrong. In any event, it has a low range ratio that could be lower for my use, and the 300 may be my best way out of the problem without spending 4 digit dollars.
My '76 CJ-7 came with the following.
258cid 6 cyl, T-150 3 spd, Dana20 Transfer case, Dana30 frt & AMC20 rear. I swapped in the T176 4 spd w/Dana300. It was a direct fit but needed a new front driveshaft. I think the rear driveshaft was okay (been many years since). o_o_o_o Best Regards, /| ,[_____], Jim, WP3JQ |¯¯¯L --O|||||||O- ()_)¯()_) ¯¯¯¯¯ )_) EM60qk 30.447439N 086.628959WDrink,
Thanks for the info.
Gordon,
Thanks for the info. The Tera gears sound like by best option, unless I want to fuss with a swap. I think you have just made up my mind for me....

don't know of any stock config with a turbo350 to dana20. AMC
J-10/J-20 trucks, the 76 CJ-7 came with an AMC turbo400 and
adapters/driveshafts for a dana300. you gain very little going to a dana300
750$-800$ -vs- 450$+ adapter, 300$driveshafts +cost of a dana300...Have something to add? Share your thoughts — no account required.
