Column shift or floor shift? What type of tailshaft?

length is virtually the same, no driveshaft cut needed.

wiring for lockup converter function?

the shaft needs to be shortened 2 3/4 in,you can use the same crossmember as the 350.you may just need to shorten the mount pad and elongate the mount slot.everything else should be as you noted above.if you have a 200r4 crossmember you will need the b body tail housing with the mount pad on it.use your old shift lever from your old trans and buy as big a cooler as you can fit. your old harness will plug in and the lockup will work.

I installed a 700R4 in my 81 Malibu last fall. I had the drive shaft cut about 2-5/8". I also cut the stock V8 crossmember twice (a little at a time) to clear the 700R4 pan and drilled a new hole. I reused my B&M shifter from the TH350.
