240zJon Posted June 6, 2009 Share Posted June 6, 2009 Okay i've searched and never really found any clear decision. which is better as a daily driver setup, the holley 390 cfm or the su's? i found a good holley carb and arizonaz setup off craiglist pretty cheap. right now my su's are running pig rich and thought switching over to the newer system would help me out. So i know rules state there is no best... so which one is better for my purpose? Jon Quote Link to comment Share on other sites More sharing options...
