What kind of front drum do you have?
Pretty sure it's stock. I think the only thing done to this tranny is a low 1st gear set, and a Cheetah manual VB. Dad built the tranny, and he's not around to ask any more.

Thinking about a transbrake for the Dart to help with my lights. Right now the car runs 11.30's @ 3000#, with a basically stock 904 and a 8 3/4 with pro gears and a spool. If I keep the launch RPM's down, will it live or will I start breaking stuff? A Dana 60 and a built trans is in the plans, but is a little while down the road. Should I wait, or will it be OK?
I've been using a trans brake since I build my car,
the only thing I would suggest would be caps in the
rearend and a back brace... I use the alum center
8 3/4 and a brace... with a 1.19 60'.... your right
at the weight where I would think about changing the
diff(to me its the weight that kills a 8 3/4)... I
use a 727 but I know ALOT of guys using a 904 with
a brake

I'm planning on changing to a better rear and tranny. Problem is it won't happen until at least after next season. (this stuff all costs money  ) Will I break the stuff I have now, or should I just footbrake another season? I really don't want to do a bunch of work on my 8 3/4, when it's coming out anyway. I also don't want to break it before I'm ready to put the good rear in. 
Continue as you are now.... that way you are pretty
much assured you'd be ok.... JMO

Just look at what happened to me when I put in a T brake with a stock front drum. 
FWIW I'm now using Mancini's nodular 489 case in my 8 3/4. I don't think it was the brake that killed the OE one though. I think it was a U joint that started it all.

OK. You guys talked me out of it. Not going to do it until I get a better rear and trans. I'm tossing around the idea of a glide anyway. No sense in buying 2 transbrakes.

I've been watching this post a little, and I love your Dart. My question is this. If you are having trouble with your lights, work on fixing your reaction time in other ways. Put a shorter tire on the front. That will help with the rollout. Increase the RPM a little. If you don't have one...BUY A PRACTICE TREE. It's the best investment I ever made for my racing ventures.
If you are bracket racing, the tire spin you will receive with the smallish slicks on your Dart would outweigh the lazy lights in my opinion. When you consider the issues with broken parts or spending big bucks for expensive drive train components...why bother. Keep your money in the bank for unseen breakage down the road. Work on fixing the problem, and you will be a happier racer. Good luck.
I don't have lazy lights, just inconsistent lights. Just thought a button would make the car a bit more competitive, that's all. Thanks for the compliments on the car, but I'm just trying to be a more competitive racer. I'll spend my money how I like, thank you. Just wanted to know if my parts would hold up, that's all.

get a practice tree and all the seat time you can. make sure your car is capable of running the number. then worry about everything else.

.....and if you want a 904/Tranz Act brake equipped 904 with a Dynamic converter built to take the abuse I just happen to know where one is sitting.
