The LS1 is a 24X EFI system......LS2/3 are 58X there's a lot more to the swap than just changing motors. You have a all aluminum V8 that can be modded and tuned to over 500HP easy.......I would be happier to know the car I was buying had a quality motor ( better rods/forged pistons/CNC ported heads ) than a plain crate motor.
