Newbie here. I have been reading for a while, but havent really found what I was looking for as far as info goes, probably my fault but would appreciate some input. I havent purchased a S197 yet and am contemplating which tranny to go with. I know once I do I will probably get a blower (either KB or Whipple most likely) and different rims to go with it. What are the basic limits that both trannies can handle as far as power mods go? There are no road race tracks close and only a 1/8 mile strip which I would like to take it on every once in a while. I am quite positive I will want to continue making mods as I have a need for speed, but are the trannies the weak link? I am leaning towards the auto due to convenience and consistency. I do work at a Ford store, in fact the 2nd Ford dealership ever, and suspect I will be leaning towards the whipple due to price discount. Until I can purchase my new ride, I will have to get my kicks from my dad's 69 Mach 1 with 351c and a 4 spd. Any thoughts will be greatly appreciated!
