what is the biggest size diameter you have fit in a 4th gen F body? stock suspension too. can you fit a 4" drive shaft in there with the torque arm?

thanks

 

I had a 3.8" carbon fiber DS, with the Spohn TA and a DS loop. There was a 4" Mufflex IM pipe stuffed in the tunnel, too.

Question is.... why? I have seen a 97 SS (3,500#) with a 3.5" Mark Williams chrome moly DS run low 8's @ 160+ MPH, with 1,350 HP at the flywheel.

 

well to answer your question, I can get a 4" d/s for $75.00 or I can order a new one for umm $400 or so. the one for $75 already has a good slip yoke for a th400 and a 1350 u joint in the rear. its just a good deal
