So your question is... What is heaver the aluminum 5.3L or the aluminum 5.7L ?
If so, they would weigh very close, with in 5#'s of each other.
Also the 1997 Camaro didn't have a ls1, it still had the LT1. The corvette received the ls1 first in 97.

Yep. I think both would weigh the same. The 5.3 has more meat it the cylinders, but the ls1 has larger pistons.
I would put my money on them weighing exactly the same.

you mite get the 5.3 cheaper ,and the truck intake is a little better flowing then a ls1 intake.I would use the engine ,trans ,and transfer case and the ECM from the right truck .you can do a stand alone ls1 engine with a elderbrock ls1 intake/ignition system.
