Hi everyone, I'm getting ready to start buying parts for my 727.
So far I know I'll be buying a steel billet front drum, a bolt in sprag. My friend and fellow member may have talked me into going with a trans brake valve body.
My question is, what else do I need to think about when using a trans brake.
Have been looking at turbo action and their shifter.
The car is still being built when I have the spare time, 70 swinger, trickflow headed 470 b engine and a narrowed Dana 60 in the back with caltrac split mono leafs and assassin bars, I have 29.5 11.5 w hoosiers for slicks and looking to run 10.00s or close, slower than 10.00s.
Anybody have any advice?
Thank you.
Also, I have no experience with transbrakes (driving)
 
Spend the money for a good converter, specifically built for a transbrake. And the rest of the drive train has to be stick shift strong. Edit: sounds like you have that handled, but make sure your driveshaft is good enough. I ran a four inch aluminum with 1350 joints and billet yokes.
But damn, they are fun. I was more consistent on the lights with mine, but that may be just me.
Lots of guys with tb use a two step, but I had a light car with lots of tire. I would just stage, floor it at the first yellow, step off the brake at the third. 5300rpm leave.

Oh yeah, this is what can happen to a non-transbrake converter....(mine).

Sounds like Fun!
 
I used a cheetah shifter with mine, worked fine. I had a very tall trans tunnel in mine, I used the button on the shifter t-handle for the line lock, and a button on the tunnel for the brake.
Lots of guys like the button on the steering wheel, but imo, that pulls your hand off the wheel. The way I had mine, when I came off the button my hand went straight TO the steering wheel.
Definitely something to play with, to suit your preference.
 
Button placement is definitely a thing. If it's on your shifter, putting the transmission in reverse can be a PITA if you drive it on the street. Especially if you have manual steering.

I have mine mounted on the steering wheel. My alignment has a lot of caster so parking is a 2 handed affair. Much easier to do with the button on the wheel

Cope Racing makes their own trans-brakes. Haven't used one but have friends that do and they've had no issues

100% agree. John built my TB 904 and it was worth the money. Best trans I've ever had. I pulled the pan when I got it to install a sensor, and OMG, it's pretty in there. Lol. Shame you can't see it

Is there a price difference between a really good converter and a really good converter that handles a trans brake, probably a dumb question.

Frankly, I'm not sure there is. All of the stuff that must be done for a tb, should be done to a quality converter. The one I blew up, was replaced by a custom built for my horsepower/torque and car weight and the tb..... and I picked up two tenths and three mph in the eighth.
If memory serves, I paid more for the converter than the trans.

Okay thank you for all the info you posted. I'll call up a converter company next week to get an idea.

I'm most likely going to buy from CRT, but the turbo action is good and a bit more budget friendly for me.
Actually I take that back, it's not a big price difference lol. Crt it is

Wow, good thing I have a big block up front.
I really don't want to be doing wheelies like that my 1st time out in a untested car lol.

Those cars are set-up purposely to do that. Getting that type of chassis reaction by accident is highly unlikely.
As an aside, when I first was driving my car after newly putting it together, I was racing at a borrowed runway dragstrip, and track prep wasn't great. I didn't think I was spinning much, but it must have been some.
Went to a real dragstrip, did my typical launch, and WHAT THE F#%k was THAT?
Oh wait! So THATS what a wheelstand feels like!?! (Was told it left with the wheels up a foot or so. )
Dang that's fun......
