mas28O Posted September 30, 2003 Share Posted September 30, 2003 I use to run 12.4@111mph with less.. 1977 280z 350 9.1:1 ported camel hump heads 480 lift cam A nice mild chevy but it would run 12.4-12.5 all day on radials. If you are running right I would say 11.7-11.9.. Mike Quote Link to comment Share on other sites More sharing options...
JB_BA Posted September 30, 2003 Author Share Posted September 30, 2003 Awesome Mike. Thanks for the info man. That's what I was hoping to hear. I should find out for sure this weekend. (Crossin' my fingers. ) JB Quote Link to comment Share on other sites More sharing options...
mas28O Posted September 30, 2003 Share Posted September 30, 2003 I ran 68 on the front and 72 jets on the back. You might want to take a jet kit with you. I have seen alot of cars run bad at the track because they did not tune it good. Quote Link to comment Share on other sites More sharing options...
mas28O Posted September 30, 2003 Share Posted September 30, 2003 Dart Iron Eagle 200cc Heads are good heads, I had the aluminum version on my 383 the Dart conquest. The first time at the track i only ran 11.6 then I had it tuned down to 10.8 on the motor. I later sold that car to 1fastz and he put NOS on it and ran 9.6. So your heads have the flow to get you where you want to go. Mike Quote Link to comment Share on other sites More sharing options...
Corzette Posted October 7, 2003 Share Posted October 7, 2003 I have a question...I have the 750DP and the stock jetting was 71 front 80 rear. It was rich as piss so I went to 68 front 76 rear so far. It is still rich but not as bad. Should I go down more? What was your stock jet sizes? CZ Quote Link to comment Share on other sites More sharing options...
