    It will effect MPG by .2-.5 mpg at the very most

    In your position, I would probably run the dual alt setup. It is a bit more work to start off with, but worth it in the end. I do not have the option of running dual alts, unless I remove my A/C compressor, which isn't going to happen. I have been more than happy with my 300 amp alt from Nate at Excessive Amperage. Running 2 2500s strapped at 1 for almost 2 years now. No issues whatsoever.

    Adds up when you drive 20k miles a year lol. But in your case I'd go ahead and do dual alts.

    Another thing to think about with HO alts... Singer alts have a lifetime labor warranty, you only have to pay for parts

    Gas mielege won't b hurt too bad with a duel. Remember the alt only pulls on the moter when you are pulling on it hard and even then only 1-2 mpg maybe. It is a shame that they charge so much for the bracket.

    You might see if they will sale just the bracket and belt cause on amazon they have a 240 amp alt with a 3 year warranty for $170.00 you could probably get away with just the one alt but 2 would be better. Add up your fuses and that will be pretty close the the ampreage you need to shoot for. .

    Things to find out. What type of alt does the kit come with? Is it a oem housing with upgraded guts? If so just buy the kit minus the alt and then buy your own 180-200 amp alt.

    Re: HO Alt vs Dual OEM alt setup

    I got lucky and they haven't sent my 270 Xp out yet so I changed my order to the dual kit with the 270xp only cost me 200 more and kit comes with everything. So I'll run my stock alt and the DC . So if I want to do changes to my system I shouldn't have to worry about power.

    O and they got some cases back from anodizing and shipping out alts this week!

    Re: HO Alt vs Dual OEM alt setup

    not sure how far the bolt positions are off from the 5.7L...i went to the local salvage yard and found a bracket from one of the early TBI trucks that came with a smog pump. mounted right up and put a 300amp ad244 in where the smog pump was. IMHO, running two completely different electrical systems was the best thing ive done in regard to my electrical.
