Just curious about how much power people are racing 727's with.
I'm asking because I may put one of my predator motors in front of one, in a 3400 pound car. The motor makes 1200 on a single 4, and the trans is built pretty strong for a 727. Billet aluminum steel shell drum, billet rear drum, Griner brake, aftermarket input and output shafts,5 pinion planet, roller, billet servos ect with billet front coan converter. I know there are other things that can be done to make them stronger, but if I have to spend 10 more cent's on this 727 I'm going to get another glide.
So in short this time, are any of you guys beating on one with that, or higher power with the trans mods I mentioned? Just don't want to scatter a good trans for no reason, and I've never put that much on one personally. Thanks.

I had one hold up real well built similarly behind my turbo car. Made around 1100hp 3700lb with me sitting in it. 3.50 gear with a 31w tire. Probably a lot more tq than the pred motor, not as much hp. I had a very low rpm staging strategy that probably was easy on the trans. That said, if you can get your money out of it to get a glide...

I really wouldn't worry about the trans durability. All the weak links are addressed in the trans parts you have. If you trust the builder, the parts will do what you need them to do.

I would put a Turbo 400 in it and hope some sucker would buy that high dollar 727.........LOL!!!! A 400 at the same strength only costs a thousand bucks, and that's just not proper mopar economics lol Really, id rather have a glide in it, just no time. Cross member, bell, wheel, D shaft, shifter

I am working with John at CRT to build a 2nd gear start 727. 1.45 first gear for my twin turbo car. He already has a 2nd gear start billet valve body with the brake operable in 2nd. I have a A&A straight cut 2.45-1.45-1 gear set. You could use a 2.77-1.57-1 helical gear set to get a little more SLR if you need it. thank you for what you are trying to do and not giving into the power guide ( taxi cab trans )
