dico...how do you like your gears? What are your rpm's at 70mph. Putting 373s in your auto is like putting 410's in a manual b/c of the orig 331 ratio. i was thinking of dropping 355's in my auto. I was concerned about the loss of traction if i add a supercharger with too low (numerically high) a gear. I've read posts by people with 410's in their manual ans s/c just smoking from a start and not getting the times they should.

 

A/T Hands down. Have had several of both and this transmission you can tune to shift at a speed or rpm. Easy or hard. No way a stick would come close to keeping up with
one with the right program. IMHO. John
