cheap power adder

Installed on my 92' chevy 350cu 5spd 4x4. Notice power right away. Engine revs up fast and i don't have to down on hills anymore. I did the jet chip, tbi spacer, headers, free flowing cat and the pulley makes more power that you can feel.

This pully was pretty easy to install. It works well and the power factor is evident. I don't know if the radiator temperature will be a factor in the summer
