With a Glebe GT6 gearbox you'd have a very durable driveline, pity to waste in the drag strip though ;) I have got them down to 6K for the six speed sequential, you can spec any input shaft and any propshaft flange. Pics to follow, I am picking up an empty case to dummy in the car, before speccing the input shaft I need and ratios et cetera.

OK, you won't get a warranty on any race box save for faulty materials. All straight cut boxes are as noisy as hell. Tremec do a six speed H pattern box that handles up to about 600 or 700 ft lbs of torque, with bias cut gears, so they'll be quiet. About $3000, maybe a warranty on it, too. Search Tremec T56, I think that's its designation.

Jamie, yea the T56 is what GM puts in the camaro/vette and other 6spd products. Tremec most likely goes in and makes some stronger parts for them but the Getrag is proven to sustain 1400whp over here in the states and can take the abuse of tons of crap.
