550-600HP 4spd suspension help

Sounds like it is going to be mostly a street car with the track so far away. You will never hook that kind of power on the street so your 4 speed will live. Just be careful on the 2-3 shift and don't smack it too hard and you'll be fine. Problems arise when you actually hook the car. In this case it is never going to happen.

exactly our track is 350+ mi away and most of the raceing around here is from a roll but with turboed and supercharged ls cars and mustangs, Iam not saying you guys are wrong its just this car has always been a 4speed and is going to stay that way its just a long long history of the car and it wouldnt be the same with a auto.

The fwd shoot for some wheel spin as to try and not bog and loose boost seems to me that this would be something to try with this dart with the tallest slick smallest wheel combo i could get to help take some of the shock out and some of the bog off the line from extreme hookup.
