You'll also need a different oil pan than the one on the engine. The C6 trans is a very HD trans but they shift like crap. You can definetly install that combo but like Kurt said it will be a dog until you start modifying the combo. I'm not 100% sure but you might need a special drive shaft also for the C6. I think that trans is longer than the typical t5/c4/AOD. If you do all the typical "hot rod" mods (heads,cam,intake,carb,exhaust,shift kit,stall converter,rear gears) you could have a very stout street car.
