i think the alt one is jsut what comes with the HO alternator....
why no on the small crank pulley?
why yes on the water pump pulley?
ok maybe i should ask another question... what will those pulleys do? i mean i get ok underdrives are better for racing, but at the cost of what? and why are they better? more hp less torque like a muffler or how does it all translate into why it works or doesnt work?
