The '68 Barracuda that I want to put the BB in, had a 318 from the factory and had the floor shift automatic. I would like to keep the floor shift auto. Am I going to run into any problems when using the BB trans?
Absolutely not, it is a bolt in. Just be sure that the big block trans has the two ears on the bottom of the tailshaft for the lower linkage pivot to mount to, not all tailshafts have them.
