I want to put a TH400 w/4'' tail in my 64 olds cutlass (same a body as the chevelle) that already has a TH350 w/6'' tail.....Chazmac said:Short tail 350 and short tail 400 are the same length, only requires slip yoke change. If you go to two piece driveshaft, use a bolt-on yoke 400 if possible.
Short tail is ~6" long
what do I have to change besides moving back the Crossmember??
sorry to wake up old thread but its very on my question
