keep the 6 speed or go TH400?
im not sure if im going to keep it or if i want to go with a TH400, now the car is a street car that sees a good amount of driving, and i do drive my car to the track which is about a half hour drive.
my setup right now is a 402 making 505 at the wheels, its went a best so far of 11.53 on bone stock 10 bolt, stock suspension, and some nittos on the stock wheels.
over winter i am going to do the suspension and rear end, and next year the car is probably going to see a 300 shot of juice.
now i like having 6 gears to ride around in, and the only cars ive ever raced have been sticks, but i want to go fast, but its still somewhat of a street car, and im not sure how much i would pick up ET wise by going to the auto but im tempted to do it, but i would like to get others opinions before i jump to it, for what i want.
theres nothing better then running great times w/ a 6spd and its fun to rag on the guys that went to autos!! plus you still get to roll race

When you are making that kind of power NA, it's a different ballgame. A TH400 w/ the correct stall will pick you up a 4 tenths or better w/o doing anything else. I highly suggest that you not mess with the stock shocks and springs until after you swap the trans. You will be surprised. We have one pulling 1.34 60's with stock shocks and springs. Ofcourse you have to do the adj LCA's and Torque arm.
Get a RMVB w/ trans brake. You'll never regret it.

i think theres a little more than putting it in D and go when you have 500+ N/A rwhp ad your throwing another 300+ hp worth or nitrous on it. i doubt that will feel like a sunday cruise down the 1320
ive always been consistent with my stick shift cars, i bracket race once in a while and im always on my dial in, last friday, non hooking track, shitty 1/8th mile times, i dialed in 11.70 and ran an 11.71 but i redlighted with a -.031 (i suck)
its not really the consistency, its the ET gains im worried about, and is it worth giving up the nice streetability of the stick for the 3 speed auto.
car is not a DD, i drive it on nice days, and to the track and work once in a while, im not doing any traveling in the car, just a car for nice days, but i do love cruising a 1500rpms while doing 70.
if i kept a stick i would like to run a 2 step, with a window switch, and never have to lift untill i hit the finish.
i just dont know how much ET i can gain by going to the TH400, as opposed to the 6 speed

all the fast guys are auto, there are only a select few that are going fast with a 6 speed.
I was in the same boat as you when I picked up my Coan built Th400 (RMVB, tbraked) to replace my t56. I know I personally got sick of inconsistancy which is the main reason I went with the auto. The stick shift car was a pita to try and get to sixty foot as well.

thanks man, are you going to be up there again anytime soon? its suppose to be nice this weekend.
im not worried about being as consistent cause all of my cars have been consistent, and they have all been sticks, its just im wanting to go fast, but i like my car as a street car, and both have there ups, and both have their downs, it just a matter of which one is right for me.
i would keep the stick if i could proshift or faceplate it, but then again, there goes the driveability. and for a clutch that needs to hold 500whp plus the bottle on top of that, who knows how thats going to feel driving and how long its going to last.
i said in one of my posts its not a DD, just a car to drive on nice days, race on the weekends, and as of right now i do drive it to the track. i want to try to get the car as fast as i can while keeping it a "streetable" car, im keeping all my power options, im keeping the monsoon stereo, along with the leather. im not going to strip it out for a track car.
i like the six speed, and its fun for sure, but i havnt had a car thats made this kind of power before and i dont know whats in the future for my clutch purchases. i want to go TH400 because it seems like thats the only way to get the car to go fast, there arent hardly any fast six speed guys it seems like, or im not seeing them.
im just stuck on wether its worth losing my overdirve gears for the gains i will see, which i dont even know how much i will gain, im not looking to set any records, just want to try to get the car as fast as possible with its setup.
For example, JL-ws6, my buddy runs a 402, th400, 5000+ stall, moser 12 bolt and on drag radials and 34XX race weight cusx 10.5X @ 127mph. A full second left on the table. But mind you depending on the converter used plan on losing 60-75 rwhp with just the trans alone, but thats ok, its not a dyno queen anyways.
