I just got my intake and 600 cfm holley installed. Idles nice and runs out great at smooth acceleration, but if ya hammer down it spits spurters hacks and coughs and gradually goes. Timing is a little advance but very little. Is it how the carb is adjusted or could it be something more like a faulty fuel pump? By the way the engine is an '87 350 with HEI.
