Just curious to see if anyone knows about them. I figure that my stock rebuilt World Class T5 isn't going to last very long behind my 420+ horsepower small block and they build them to handle 600 street horsepower. Prices are a little stepp but hey, you get what you pay for, right?

 

Yeah, I bought an upgraded syncronized T-5 from them a couple years ago and it's hanging in there just fine. But keep in mind that I don't have a posi - yet. Since I dynoed at 390 flywheel hp, and 490 flywheel torque on the engine I have installed now, I'll be consevative and say I have at least 420 TQ at the rear wheels.

Great service - if you don't expect call backs, (they're lousy at calling you back) and you'll need to get over the fact that one of the lead guys there is named "Bubba"....

I have the optional .59 ratio 5th gear, which is great on the highway! You will need to use thier GF3000 additive in the trans, which costs like 38 bucks a quart, but it's good stuff!

 

I plan to go with Gforce when my T5 blows up ...
