Surging at wide open throttle

hello everyone, i have a 67 camaro with a 30 over 350, th 350 ,edelbrock intake and edelbrock 1406 carb.hei dist. cars runs awesome at idle, and at cruising speeds. when i am cruising at 45 and floor it, it kicks down to a lower gear and goes great but then it starts surging at higher speeds like its starving for fuel. if i let up a little bit its fine, just cant keep my foot in it or it will surge. any ideas? is there a metering rod in the power circuit to allow more fuel at wot? thank you..kris

Re: Surging at wide open throttle

might be an ignition miss!
90 % of the time a surge is an ignition miss.
check wires and cap/rotor.
plz tell me your not using taylor wires!
they are pretty but dont last long.

Surging is a sign of a lean condition.

yep souns as if leaning out....I know nothing about edelbrock carbs, but sounds like bowl level, and/or fuel delevery....eg blockage of crap in filters/lines

My Spelling is not incorrect...it is creative

What he said. Could be a vacuum leak or a carb that needs to be rebuilt or recalibrated (enrichened).
