choosing an alternator

[krazykyle]

I'm looking for an alternator for my 83 olds.the problem I'm having is that i have a deeper pulley on it and at low rpms doesn't give me enough juice to power up my lights and then when my electric fan kicks on lights get dimmer yet.anyone have a good answer for this one.i'm running a 350 chevy with a large cam and 456 gears if that helps.

something like this should speed it up if you have the big pully that looks like the wheel from the price is right

also try doing a cs conversion I got mine out of a buick roadmaster from a junkyard 140 amp

i have a deeper pulley so i won't throw belts.what alternator will fit that car that has a higher amp put out.

well since I'm going with a 140 amp alternator will i see anymore performance in my car.will a higher amp output affect my car in anyway.

The only reason you would need a 140A alternator is if you were running like 12 TV's throughout your car
