I am thinking this so you all help me out, It might be advanced a lil to much, It is hard to start, even turning it over then hitting ign switch, which after breaking two starters last month is the way I start it now, It will be 180, run down the quarter and she is always over 200 usally around 210, it was nice and cool, 85 or so when we got there, down in the 65 or so on last pass, and it still would heat up like that, it is timmed at 38 also I changed heat range on plugs went to a 25 autolite have always used 26 , but I dont think that is it. On new carb it has no powervalve in back, and have 76 jets, 72 in front with a 6.5 powervalve, like I said it sounds good down low, lifts front and goes, so that was good but over 5000 its missing like, wanting more fuel or something, yes I have a holley blue pump and my pressure I pay attention to, like every gauge I have, it is set at around 6.5 pressure always below 7, but at 5,000 or so she was bounching around a bit between 5.8 and 6, was wondering if that could be it but it is close to 6 and have heard that is fine, it a few times was at around 5.8 -5.7 in the upper rpms, My ignition stuff is hei, with a pertonix coil and pertonix module, no box, class is now open, back timming down some, 80 jets in rear, adjust fuel pressure up a tad, get a new door handle for passenger side LOL :lol:
