I'm in the process of redoing my formy, it's currently just a bolt on car. But I'm putting together a little 355 LT1 that will be making roughly anywhere between 450-500hp on motor. I'm still purchasing the parts for the new engine, but I'm not going to stop there.

I'm going to pretty much replace all of the drivetrain and suspension, even the k-member. I'm doing my shopping right now on TH350's and TH400's. And I am trying to figure out if I should or should not run a trans break.

What are the pro's and con's? Obviously it will take me alot of practice to learn how to launch off a break, but I am not sure if it is even worth it? It's going to most likely have a 3800-4000 stall in it, and it will be driven on the street on the weekends between the track and car show's etc.

I'm open for opinions and ideas....

Thanks,
Mike

 

Trans-Brakes are good for only one thing, and that is consistency for bracket racing, and that is it. It is much harder on the driveline, and many vehicles actually have quicker 60 foot times with a foot brake start. Again consistency is all that it is good for.

 

Thank's for the info. I guess I just figured that the trans break would help net better 60ft times. Is there any truth to that? Or is that mainly for wilder engine combo's?

TH350's are great for reliability and consistency but if you EVER need to drive over 65mph and you have a gear higher than a 3.42 you'll be winding the engine past 3500rpm. I knew this was the situation i would be in, but for the $$ and the fact that my car is a weekend show driver I went with the setup. Also you cant beat the fact that a non-lockup stall converter for a th350 is around $100-$150 versus around $500-$800 for the ones you get ripped off on for the 4L60 trans.

 

A GOOD converter is more than $100 to $150 no matter what trans you have.
