I am looking for opinions from those that have done either. I have a pretty stout car that will run 10s once the tranny is figure out. (already does ~100mph in the 1/8th) My question is this, OVERALL which is the better option, I am taking into consideration 1)Price 2)durability 3)street manners. this is a car that is not a daily driver but will make 100mile round trips occasionaly. (to the track and street prowling) I know the 200s CAN be made to work, but will I have to rebuild it often? I KNOW the TH400s are proven beyond 1000rwhp. basically what I am looking for are people who say "I went with the___but in hindsight I wish I would have done ____" any input would be appreciated.
