Surge Problem
Hey guys, Just built a 347, and got a surge problem, When I`m at wide open throttle, its pulls like a freight train. But when I`m cruising around town, it bucks and kicks like a mule. Got 30lbs injectors, and stock for now pump, (just bought one), got a 190lph pump, and a adjustable regulator, just wondered if that is the problem. Cam is 544 Intake, 573 Exhaust, 238Dur @.50, 248 Exhaust. 70mm TB, and 75mm MAS, TF U/L. So if anybody knows or delt with this problem, please help me with this, Thanks alot for your time...

do you have the correct calibrated mass air, and do you have the idle air control valve"spacer" it goes between the iac and the egr plate and has two allen screws that you turn in and out and it will correct surging idles, and some driveability problems, you can order this spacer from your local ford dealership for 15-18$ if you already have all this i would say a vaccum leak. hope that helps
