We run that set-up on a friends 440. 600's, stock jetting. Accelerator pump rod in the hole closest to the carb throat. Car runs(11.50@115). Depending on your cam you may have to change metering springs. With the car idling in gear loosen the metering rod/piston access cover. Rotate it and watch the rod/piston assy. If it's bouncing up and down it needs a lighter spring. If not you can go stiffer to help with mid range. Even my 15-1 572 with a [Email]285@.050"[/Email] cam runs only 2 sizes up on the primary's, no chokes and a 2nd inlet line. Other than that they're out of the box (9.25@147).
good luck

Exactly... "Pay attention to the needles at idle".

Edlebrock has online the owners manual. Read it a few times until it "sinks in". Be sure to read it again after the the first time running the car also. All the "bulbs will come then"

I've been tuning that carb since 89 or so. I have been all the way to 14000 feet with my 1405.
