i currently have a 700r4 in my 89 camaro and am in the process of building a th350. whats the length difference between the two driveshaft from r4 to 350 and is there on out of another car that would work, i have herd a driveshaft out of a 200r4 would work or would it be easier to have one made. thanks for the help

 

Assuming you have a short tail th350, an 82-83 driveshaft from a th200 f-body would work.

A 700-R4 Caprice driveshaft is 2.92" shorter than a same-year 200-4R Caprice driveshaft so that length longer than stock would work for you.

If you had a long tail th350, you wouldn't need to change driveshaft.

 

correct. 6" tailshaft housing will need the th200 length driveshaft, 9" will use the 700r4/T5 version. and (in case it slipped your mind) don't forget that a torque arm adapter is required for these cars if you're tossing in a th350 or 400

 

Hello, I was wondering if you had any luck with this. Also I was wondering what the drive shaft length is for a TH350 in a 3rd gen?
