Hi my name is Shon. I drive a 96 ws6 trans am. Im wanting to swap the front bumper and hoid on this car to a 98 ws6 front end and hood. From the threads that im reading this should be an easy bolt on swap. Im also wanting to swap an ls1 in place of the lt1 is this an easy swap and will the ls1 bolt onto my m6 tranny or am I better off just building up the lt1? Ive found a head csm combo for a fairly decent price. The car has 108, 000 miles on it not bad for a 96 but soon it will need a rebuild so thats why im thinking a ls1 swap. Any guidance will help. Thanks
