Re: 140 Amp Alternator
would these be using aftermarket internals to get the amperage? if so, whats the output at idle speeds?
FWIW - the GM late model vans use a CS 130 (130amp) alternator that'll put out closer to 150/160 amps if you use a low resistance ground wire ( ie welding cable) direct to the alt. its a stock GM 'big body' alternator, using normal GM style mounts, you just have to swap the pulley, as they're mostly fitted up for serpentine belts.
