Check the adjustment on the accelerator pump. I don't know how to
say this properly, but it might be getting "too much". Loosen the
pump arm a little see if it helps.....or change pump cams to one that
pushes the pump less or slower.

I have a Holley Avenger, 570, on my 65 327with a mild Lunati cam,
just can't seem to get it right. It has a bad stumble when
accelerating. Playing with the power valves and the jets now hoping
to solve the problem. Been a nightmare, but has lots more on
acceleration than the Edelbrock 1406. Any suggestions on the stumble?
