There's really no difference working on an LT1 car vs an LS1 car. It's the 4th gen engine compartment that is FTL! Stop whining until you have to change out the passenger side AIR check valve on a 93 LT1! The LS1 was a bigger PITA when it comes to the rear passenger side spark plug and wire when doing headers and I've done them on both engines. The best thing about the LS1 is that it makes a good 30-50 hp more than an LT1 with the same mods and still idles smooth as can be and passes inspection easily!
Radiator! Give me a break!
