Just read in GMHTP that they are working on a six speed manual tranny strong enough to hold up to the upcoming 600+ Supercharged 6.2 litre LS9's horsepower , and I quote "It's got to be one hell of a tranny..." This will be going into the upcoming Corvette SS aka "Blue Devil". Can't wait to swap it in. But if it was me I would've done a Supercharged LS7 w/ low compression heads...So who's gonna beat me to it...Hahaha...LOL
