Hi Smart People!
I have finally got the engine running with the Holley 390 and am having trouble with bad hesitation. It idles fine, pulling about 15 on the vacuum gage, and I think I have the timing pretty close. I really need to play with the gas pedal to get it to go, and even then, a lot of hesitation. It still has the stock main jets (51?) and I figure I need to change. I have searched the forum and found a couple of references to 54s. (I live at sea level, moderate temps.) Is there a method to reduce the amount of trail and error or should I just wait until the local Holley expert can pop by? I reckon I should have an assortment on hand.
Cheers!
