you can get a v6 electric taurus fan from a junkyard pretty cheap and they do a really good job at keeping the truck cool. 90+ degree days and I have to turn the ac down cause my fingers won't come off the steering wheel! Although nate is right, they do suck a lot of power.
I have seen a 200 amp alt for $189, which is a pretty good deal in my book. Somewhere out in tx sells them... alter power or something...
..also, toss the hype +4 plugs.. they are not doing anything for you. stick w/ the stock ac delcos, or go with ac delco rapid fires.
you could do a ram air setup off the snorkel of the air cleaner, that would give you some more top end. There's also headers, exhaust, computer chip, etc etc..
i didn't know that there was a ram air setup i could do to it. what would a 200 amp alternator do? right now i'm just running single 2 1/2 inch exhaust. ive been having problems finding computer chips for it. do you know where i can find one?
