I've heard the same thing about manual trans on another forum. Some of them can't handle the torque.:_paranoid

Great build man, should be a blast to drive :cheers:

1200 ft/lbs of torque is going to hurt any tranny LOL I think your thinking is right tough that a TH400 with gearvendor overdrive is one of the few boxes that can be built to take that much abuse. I would run a manual trans however I think I would probably have a little less power then you. hehehe

Tonny

The nice thing is the 400 can be built with engine breaking and the gear vendor gives you 6 speeds. If the auto (really a manual automatic) robs too much power I can just add more boost. :P I'm pretty sure it won't be an issue. I was also probably going with a bolt together torque converter so I can change the stall speed myself. If I do the 400 i'll let you know how it works out. :cheers:

Im running a 400TH with gearvendors on my big-block and love it. No issues with it and you can split shift as you said a 6 speed auto. Its a great set-up.:thumbsup:

Good to hear! :cheers:

Are you planning to drag race the car with the slicks or just road race it? I'd be willing to bet that if you're not planning to drag race it that Rockland Standard or Liberty can build you a transmission that will hold up. It's worth a call at least.

I do think the 400 with the GV unit would be a better choice though. You'll have enough on your mind while piloting to worry about. No since in making gear selection anything more complicated than just tapping up or down on a lever or paddle.

The car will be drag raced as well, mostly to tune it up for a 1 mile event. The problem is usually the same, and I have talked to liberty, jerico, lenco etc. They don't make the strong transmissions or gear sets with over drive. Thats the only way the car can reach its top end. There was one or 2 companies that did but it was barely an overdrive, something in the .9ish range. Thanks for the input though, I will check them all out again before I buy.

Your experience has been better than mine, I'm not happy with mine at all,noisey on down shifts ( clunks ) ,not enough overdrive,and gear vendors tech support has not been much help, kinda feel like they don't no their product very well. Just my.02 . love this project !

Hey...do I know you? Some guy that lives by me and calls my house at all hours of the day has the exact same car...if you are talking too him kindly tell him to F&*k off :)

all kidding aside..

This car is really fantastic up close as well. Steve's attention to detail has been unsurpased. I remember sitting in his living room and we were talking about this type of thing as a pipe dream and now its really comming together. Like anything this build has caused numerous frustrations, more money than expected, and some time frames didn't go as planned but when all is said and done he really has created a great piece of machinery ! Steve loves to go fast....so do I but I have my limits...not sure Steve has found his yet :)

I will stop writing now as I am getting teary eye'd :)

not bad for my first post eh Johnston :)
