Just a followup, info for anyone using the newer Edelbrock 800cfm carbs. For the first few months, the 440 started fine, but would hesitate on acceleration. Played around with timing and tune, but couldn't seem to shake the hesitation. The Edelbrock 1813 carb came with the accelerator pump linkage in the top (biggest squirt) position which Edelbrock recommends for a large cu in engine. One day on a hunch, I reset the linkage to the middle hole. This solved the hesitation.
