I dont know if its OK to pimp another site here, but this is for guys that like to drag race with manual transmissions, not much info about that here.

Great site with lots of trans / clutch / gearing info, check it out

It is a cool site. I checked it out. Thanks!! My 1969 Camaro has a Super T-10 4 speed w/ an aluminum case but I'd still take a well built automatic with a nice stall & full manual valve body each and every time over a 4, 5 or 6 speed manual trans that Detroit has to offer in any of their cars.
