here to learn about swapping in an ls into a 87 chevy 1/2 ton. engine is out of a 03 burb, plan to use the original 700r4 trans. looking for pointers, dos, donts etc... perfer to buy a stand alone harness vs doing myself. looking to see if there are any drawings out there to fabricate my own motor mounts ( im a welder) also wanted to get the perfered method on flywheel to the old style trans. not sure if there are products that have been found to be superior from the rest? I'm kind of looking for cheapest but sufficient swap parts. Thanks!
