I got a $378 shipped version from Summit racing with the 15% ebay coupon they had the other day.
However I ended up getting the 8.6" (8% Overdrive) pulley instead since i dont plan on running headers.
I am not getting alot of information when searching on what belt to use with the Stock upper 2.5" pulley and the 8.6" Lower pulley.
If you used the GATES Greenback k080845HD with your 9.1". Mine belt should use a slightly shorter belt. The next size shorter is the K080842HD belt. It is only 3/8" shorter. The circumference difference between your 9.1 and my 8.6 is (.5 inches x 3.14159) or about 1.57". If you subtract that off your k080845HD size its about the size as factory which is the next size under the K080842HD belt. So it appears the factory size might work, maybe????
So does anyone have an idea on what belt I should get. It appears that running just a lower 8.6" pulley with stock upper is not a common combination. Its about the same blower speed as the 2.3" upper though.
