    Just a quick question...

    What is the size of our stock upper pulley? I switched pullies around and can't find my original one to measure. I had a 2.4" + stock lower....just switched to a 2.6" upper + 10% lower.

    Want to be able to accurately compare psi when all is said and done...

    Stock upper is 2.7", about 14 psi stock.

    I have a stock one if you need/want it. Just pm me if you want to work something out. Otherwise I thought the stock size was 2.67 but I could be wrong. Either way I don't think there is much difference psi wise between 2.7 and 2.67...

    I had the 2.4" upper and stock lower running stock manifolds and an O/R H...PSI was right at 17lbs.

    I just switched to a 2.6" upper and a 10% lower running AR headers and an O/R H...just from the test hits on the engine break-in I was seeing right at 15-16lbs...hoping it will be MUCH higher once we start the FULL tuning from Lund...

    General consensus is a 2.7" upper, stock...that sound right?
