when i did mine i jsut had the short block in the car so it wasn't too bad just make sure you get it in there straight cause your alingment will be based off of how it goes on the car if it's not centered then that will throw everything off it shouldn't be a big deal just wanted to warn you and they can check it afterwards when you get it lined up . if you think about it ,weight your stock parts then the aftermarket to see how much we have lost with this mod?
