    I'm going to go out on a limb and say, no way...those two engines are from different worlds. Just eyeballing the intakes you see major differences. The 5.3 is plastic or composite and the lifter galey is sealed off by a plate rather than the bottom of the intake itself.

    If you're looking for more HP, try swapping out an intake from a camaro or firebird with the 5.7...and TB, and injectors, ect ect...

    Basically nothing from the new gen LS small block swaps to the old SBC series (265-400ci).
