hey guys, im almost done building a big block chevy for a project that im doing. the motor is going to have roughly 500 horse, and i do plan on spraying it about 150 for racing purposes. its mainly going to be a street car, but it will see some time at the track (not alot, i live too far away). anyway my question is, what manual transmissions are out there that can handle that type of power? I fully understand that a turbo 400 would be my best bet, but i really would love to put a stick in the car. i can't afford a tko 600...so thats pretty much out of the equation


any input would be greatly appreciated

i know there are a few people running around with supercase m22's without any problems..problem is i can't find a website that makes them? anybody have any ideas?

There are a few options for manual trannys that'll handle 500 hp. The problem is that none of them are cheap. 500 hp is a lot of power. If you want to play you have to pay. The tko 600 would do the job well. Anything from g-force, liberty, or jerico would also work and would actually be overkill. A T56 should handle that power assuming it's in decent shape. If you're launching with slicks on the track, that could be a different story.

Yeah on the "overkill". The reason I went there was in view of the natural progression of things. He is talking about spraying 500 hp with another 150 for racing, that usually and eventually winds up with a guy launching on the bottle (and slicks) and after a season or two of the small blocks chasing him down, stepping on it again to make it go a little better. I won't be surprised to see him here in a couple of years asking for recommendations for gear boxes to handle 900 hp lol. I think that "G" Force prepared T56 will work pretty reliably without all that shaft flexing nonsense ruining his fun and it will retain it's value while delivering a couple of years of reliable performance even with some engine upgrades. That GF5R could be the last tranny the guy would ever need.

He did make mention of economics and the way I see it, setting it up right once is always cheaper then 3 or 4 times wrong. From where I sit and have sat, the Muncie will be the most expensive and the most disappointing one out of the bunch (long and very short term).

Just my opinion.

I totally agree. The g-force T56 looks awesome. And in the long run the extra money would be worth it.
