Well i went back out to the track tonight and ran 12.14 at 121mph with 23 pounds boost, second 12.37 at 123mph with 25 pounds boost. Then the head gasket blew on the 123mph run. So i'm done for this year i have to change the head gaskets and the transmission will come out and get rebuilt along with a Precision 3600 stall. BY the way i am still running a stock converter that is why the ETs are bad but good MPH. I need to go to a 28" slick i run a 26'x10.5 street ET now. Rob
