I'm starting a thread about additions available for LS motors I've found. Mostly external parts. Post up something cool if you want. I'll start off with a dual alternator bracket. Biggest alternator I've found for a LS is 400 amps. Dual would give 800 amps in case you need to winch up mount everest.
