fourwheeler75 · 10-11-2009, 07:09 PM

i have just swapped my 700r for a brand new 350 turbo.... i was wondering about the drive shaft i know the 700r one will not work. but i was not sure if there was one i could get out of something else that would bolt in or if it was just easier to go have one made any kind of advice would help thank you .

I've seen 700 to 350 direct swaps, depends on the tailshaft.

Try and put the driveshaft in. I put an 8.5" rear in my car and needed to shorten it 1" but we went with 1.5". The shaft was out of balance so they just made a new one instead. Your best bet is to just try and put it in with the truck on jack stands in the back on the frame.

Also like to add, it depends on your engine mount adjustment.

I don't know of a bolt in. I had to get one made for the 350 transmission. The original shaft with the 2.8/700R fit the 5.7/700R

If the 350 has a 9 inch or so tailshaft, it would only be 1/8 inch smaller than the 700r4. You can cheat and make that work with the existing driveshaft.

You probably would have to move the transmember.

Probably take a dremel or a drill bit and elongate the holes for the trans crossmember if you were really concerned about that 1/8 of an inch.
