Summit Racing Underdive Pulley
I just finished installing my Summit Underdrive Pulley and am quite pleased with it. It looks quite well made, especially for the low cost. I had lost some low end torque with a cam and noticed an improvement after the pulley. The install went fairly easy (after getting the steering rack out of the way) and it fit just like the stock unit.
One thing they don't say on the website is you'll need a 41" belt for the A/C(stock is 42"). The 78" belt is the perfect size for the serpentine. I would recommend buying the belts locally as they're a little overpriced on summit.
They also didn't mention that it comes with a key way just like a powerbond unit, so it can be used with a keyed crank.
