Cool cool.. i just remembered that i put some 89 octane in it last time.. maybe i shoulda put 91. I'm going to try the holley 650 with no carb spacer and leave the current intake on and see what happens. I'll let ya know about the carb Brett..... I just drove by the gas station.. 91 octane is 2.30 a gallon... man that sucks. At times like these i need a 4 cyl just to be able to afford gas!
