You're splitting hairs.

Sure, one can't go to crazy high boost levels with a non-built LT1, but then you don't have to, a Maggie will give you the same power at 7 psi as the LT4 can push at 11 psi, plus you'll have cooler IATs which helps with longevity.

The brakes are a bit better on the ZL1 (390 mm vs 370 mm front discs, the rears are identical), but smaller rotors are also lighter and it isn't like you couldn't swap the ZL1 brakes onto a 1LE or even on a plain SS.
