i haven't had an lt1 in a car that it didn't come with but my friend put one into a grand prix and when he tryed to start it, it wouldnt start later to find out that the crank position sensor was bad. i am sorry i don't know of anything to help you besides that little tid bit or try to find someone who also has an lt1 that is still computer controled and try and swap the computers....... my friend also did that, his motor came out of a camaro and his dad had a 96 caprice classic. best of luck!
