Re: 700R4 conversion to Dana 20

Mike34 the advanced adapters chart shows different part numbers for the turbo350 and 700r4 trannies.700r4 #50-6905 the turbo350 #50-3001.It also has notes stating for long wheel based vehicles. Just thought you should know. I thought about this my self, but i have a commando 104" wheelbase.The list is $717.15 thats pricey.The catalog also says to use the 2wdoutput shaft.I'm going to look into a sm420 or sm465.

Re: 700R4 conversion to Dana 20

thats kind of an odd combo!
itll be long weak and expensive, is it really worth it for the OD?

I guess if you Highway travel alot it could possibly be worth it, after youve driven 70K miles you might recoup the extra cost in gas, maybe.

Re: 700R4 conversion to Dana 20

What's weak about it? 700R4's can handle high HP motors, Gear-driven Dana 20 xfers can also handle V-8 power.

I agree that it'll be hard to recoup the time and expense of a conversion, but sometimes we just like to do things like that to satisfy ourselfs.

I'm running Buick V-6/700R4/Atlas II 3.8 in my Jeepster. Will never recoup, but it was a good challenge.

Re: 700R4 conversion to Dana 20

Ive just never anything good about a stock 700r4 being strong at all.

Im sure you can build them to be really strong, but in the stock form they arent nearly as strong as the dana 20 on the back of them.

No biggy, Hell put a Ford engine with a chevy tranny, and a transfercase from a Nissan patrol, then run some Rover axles if it tickles your fancy!

Im just a tightwad, and I hate to spend money on adapters.
