Hello to all. I've got a question for you FE experts. I've got a 406FE from Southern Automotive with iron heads, aluminum intake, Holley 750cfm carb, turkey pan, and a Crane fireball ignition box and coil.

I've had problems with it misfiring. I readjusted the accelerator pump and it now accelerates fine, but if you are just loafing along, it misfires. The timing is set for 36-38 degrees advanced at 3000rpm (about 12 at idle). It starts instantly and idles smoothly. The plugs look as if it is running a bit lean (the color is between white and tan). Where else should I look?

Thanks in advance,
Bruce
