View Full Version : TH350 swap driveshaft ?

04-08-2012, 07:28 AM
Doing a TH350 swap into my LS1/4L60E swapped 96Z28. Tried searching for the measurements for driveshaft that will fit a TH350 short tailshaft to a stock 10 bolt.

I know Spohn makes a ready to drop in driveshaft but I've heard of fitment issues. Been looking into Denny's 3" 1330 series or PST 3" 4130 series but need correct measurements and I don't have time to do the swap, measure and wait to have the driveshaft made since I'll be borrowing a friends backyard for the swap.

Any help is greatly appreciated.
Also any suggestions on my swap? I have a TH350 6" tailshaft I believe, Hughes Flexplate and spacer, modified BMR crossmember, Lokar 36" Dipstick. I believe the trans already has the VSS and gear installed since the trans came out of a LS1 F-Body. How would I check?

No one has measurements for a TH350 to a stock 10 bolt?

I want to say that I've seen you can use a stock shaft with a th350 but I could be wrong. I think thats with a 9" tail but I dont know how many different tail lengths there are

You can use a stock length driveshaft on a long tail TH350( 9" ), but it is still a little short

If you have a short tail ( 6" ), add atleast 3" to your stock driveshaft
