The P/S pump (driver side, above the alternator) wouldnt be a problem

The alternator (driver side, below the P/S pump) doesnt look like it would cause issues either.

Kwik performance makes a bracket that raises the compressor up near the valve covers (almost $200). I believe Dirty Dingo makes one also.

Buuuuuuuut, the LS1 is also drive by cable. I was just starting to get comfortable with the idea of DBW... I havent seen a build thread that mentioned DBC. Is it a pain to tackle?
Ive owned both & built many more, GET THE LS1. The DBC is easy....Dont let that scare you.

The aluminum 5.7L LS1 is NOISEY when cold....Or should I say noiser than a 5.3L.
