The 93 LT1 is quite a bit different from the 94 on up. There might be some sensors missing from the 93 so you would need to use the 93 wiring and computer to make it run like a 93 which is speed density. It wouldn't be a straight swap, that's for sure. It has nothing to do with Pontiac LT1 vs Chevy LT1 though. So yeah, he was talking out his rear again!
