for you V8 guys out there. Which auto trannies and transfer cases are you running? i wanna auto for my 350 and might as well go for a new transfer case instead of sticking with the Np231 and buying a $431 adaptor. I would also like to do it with as least adaptors as possible. i wanna an auto because I think its cheaper plus this is going to be a daily driver, call me crazy.
Well I'm not going to use the Np231. If I'm going to do this swap might as well do it right the first time eh. So what are some trans/transfer cases that will bolt and up and work great in a in jeep that runs off a Chevy 350. Remember Automatics!!!! Too much money to put in a stick I'm kinda on a budget. Don't you have to flip the 300 to make it work in a jeep with the stock D30 axle. (oh yeah I'm keeping the stock front axle.) Whats a transfer case that will work with out fliping. i.e. driver side output for front axle.
I already mentioned the three auto trannies that will work on the Chevy 350. Take a look at Advance Adapters or Novak Adapters websites for transfer cases that will adapt to those transmissions. Most Chevy transfer cases that are worth a darn are passenger drop, so you're going to want to adapt a drivers drop tcase to the Chevy tranny. Really there aren't that many options for you to pick from, so don't go looking for lots of info. There's always Advance's Atlas tcase, but you better be ready to pony up some serious $$$ for that one.
You might think about a turbo 400/D18 combo out of an early Wagoneer with a Buick 350. My memory is hazy, but I belive that it was also offered with a D20 transfercase as well. This will be a direct bolt up to your GM motor with the adapters already in place.
Jeepdaddy the T400 with either a D18 or D20 or Quadratrac for that matter won't work for him. He wants a tcase with drivers drop for the front driveshaft. All of those are passenger drop. Also, the T400 behind the Buick won't bolt up to a Chevy 350 as the bellhousing pattern is different.
I am running a 350ci engine, with TH350 tranny and NP203 T-case .. but I also swapped my front axle to match the passenger-dump of the T-case .. and while I was at it, I put a stronger rear-axle in as well .. and made it all SOA.
If you want to keep your front D30 .. then I would get a 1988 or newer T-case out of an IFS Chevy-truck as they use driver's dump.
