Hey Guys, Maybe someone on this board can help tune my Holley 750 DF/DP. First off the engine, 400 pontiac bored 30, trw flat top pistons, crane hydraulic 560 lift w/ 1.65 steel rockers, 1968 #16 heads ported, bowled, 3 angle valve job, holley street dominator. The carb is a holley 4779 750 DP/DF like I said prior with a proform center section, primary jets at 72, secondary at 84. Next the problem, engine just does not want to idle, when you think you have it, it gradually slows down and shuts off. When you increase the throttle screw for a higher idle it seems to hold but fluctuates up and down about 200 rpms. Any help will be appreciated. If you need any other information, post here and I will try to get the answers for you. Thanks in advance for your help guys.
 You Have To Be Willing To Take It To The Max!
