I am looking into buying a six speed overdrive and I was wondering if anybody installed it in their chevelle and if they liked it. D&D rebuilds the viper tranny to fit any early chevy, They also claim to handle up to 650 lbs torque.
Anyone have any suggestion thanks

I was told by D&D that a stock Camaro/Firebird trans is good for 750hp max! They rebuild THOSE trans to "Viper" specs, which is suppose to be good for 900hp max! With my engine/ car set up, they told me they would recommed a stock Viper trans. The shifter location is a few inches forward compard to the Camaro/Firebird trans. With this trans your shifter location is very close to the stock, letting you run a stock consol if you wish.

I have the engine and trans mounted in the frame. (which is on jack stands) Street & Performance has a guide on how to put this trans into a 70 Chevelle on there web site. www.hotrodlane.cc

Thanks a lot let me know how it works out.

I have their T56 Viper trans in my *cough* Mustang *cough*.

With 3.73 rear gears, in 6th, at 2000 RPM I'm at ~80MPH.

I believe Clint44 does. A stock LT1 T56 can take more abuse than most give it credit for especially if you do not drag race on slicks.

I installed a Rockland Standard T56 in my '67 Wagon with a hydraulic clutch kit fron ATS (www.t56kit.com). It's pretty slick.

Rockland also claims 750hp for their T56s, which are upgraded over LT1 specs with the 30-spline Viper output shaft, carbon fiber synchro rings, and a steel 3-4 shift fork. That seemed like a lot of trans for $2,200.

The ATS kit is cool- They used my '67 to prototype the A-body kit, so the crossmember is right on. The only downside is how much of the factory floorpan needs to be removed, but I wasn't worried about it. If I had a "matching numbers" SS 396 or something, I may have had more reservations. Since I have an original 283/PG wagon, I couldn't care less. The 383/T56 combo is well worth the new trans tunnel.

Yep,it's worked pretty well,so far.

have you tested it on the track or punched it all, and if so how did it respond thanks

have you tested it on the track or punched it all, and if so how did it respond thanks I have a D&D T56 in my El Camino. I've hammered on it on the road course and the drag strip. Holding up fine so far. I really don't expect to have any problems with it.
