So Im looking to get a few more ponies out of the 4.3L in my truck at a reasonably affordable price. Im looking at getting an underdrive pulley set to start off. First, is there any worthwhile difference between, say, Auto Specialties pulleys and March Performance? The The $40 difference has me leaning to Auto Specialties.
Also, Im looking to get rid of that 15 pound lead weight of a clutch fan and put an electric fan in. Any suggestions on an ideal size, etc to keep the truck cool? We're shooting for the 160-170* mark. Something with an adjustable thermostat would be nice.
I know this wont net astronomical improvements, but I think it'll be noticeable on my lil 4.3L. Its also to help my truck along while running the AC.
Thanks.
