street/strip engine question

With an idle with 8" vac. it must be fairly lumpy, so the wide band won't be very accurate at idle but will be useful above that,

@ idle is the issue. way rich. have been all through the tuning to no avail.

What have you tried?

Does that carb have the holes in the butterflies?
On Dominators I've had success with restricting the idle feed holes.

thankyou everyone for all you help. best i can measure today is .090'' on the idle feed restrictor....this restrictor i was unaware of, therefore its factory size and untouched.

Idle fuel bleeds are too large.

Yes, idle feed restrictions could be a bit large. Did you plug the secondary P.V. and go up 5 or 6 numbers? How much base timing, and total?
