LS1 underdrive pulley Identification??????? I got this pulley off of the same car I got my headers and everything else. Not sure what brand it is, anyone else here know?? I am thinking about going with the stock pulley and selling this one so the engine will run cooler. It has never overheated, but when I put it back together with the 160 t-stat and fan switch I want it to run as close to 160 as possible.

Looks like a clone of my ASP pulley. I'd put my money on the fact that it's an ASP. I've got mine sitting infront of me right now (still was in box.. gotta put it on) and it's virtually identicle.. you'd think the company would put a part# on it though!!

Didn't ASP send out a bad batch of pulley's at first that were supposed to cause some vibration at the front of the engine which the ecm picked up as spark knock and retarded the timing a bit??

I'm looking at an ATI damper/pulley combination. The machinist swears by them and since I don't want to do this again, I want to make it right the first time. Any thoughts or comments on that subject will be received and considered.Thanks
