yep... one of the guys who swapped an LS1 into a GTP was Tom Killgo. They had to do alot of custom work on the front cover. Its together and running, don't know what happened to it since. Loyde from Fast Fieros did the swap and fabbing on that car. IIRC it was stroked and bored, headed and cammed. Sounded pretty nasty from what i've heard. If it was my car, I would of just switched it to RWD, I think it would of been easier in the end...
