Truck has P/W, P/DOOR LOCKS, P/BRAKES.
Have upgraded: stereo, also larger alum. radiator W/dual elect. fans (38amp. full load 6100cfm), elect. fan on trans cooler (14amp. full load), I am planning to upgrade the charging system and add another battery, however I'd like to know where I'm at to begin with. The engine has been upgraded to a 383ci 4bolt, built for pulling.
I pull a 24' pontoon boat with little effort, however the cooling fans run about 70%-60% of the time and I don't want to be using a lot of time developing an adequate system, but I need to know the original output, any help is deeply appreciated, Thank You!!!

    Agree with #1 answer, look for amperage on the rear of alternator. "Most likely with 130mm (5 1/8 in.) Diameter Case; with Optional Electrical Equipment (power windows, trailer wiring, etc); 105 Amps. Information copied from rockauto.com".
