Dyno,
If I remember correctly, you and I are both slightly over-carbed running 850 holley's on 461's. Combine that with the heavy weight of a Sonic (or in my case a Formula) and a single plain manifold, I think it just wouldn't have the midrange. If I'm not mistaken, can't you more easily get away with a large carb on a dual plane than a single plane?

5200rpm's ? That's where thier just starting to run good
I was under the impression you would be spinning it higher. That is why I thought the single plane would be better than the dual.

On my version of Dynos 454 on roids I ran a match ported oval port Holley Strip Dominator manifold with a 750 DP. The boat ran awesome from 1500 to 5400 RPM. Smaller boat though.

Just get the Mrs down there with a big bunch of towels! Tell her you'd do it, but you don't fit; since she's so nice and skinny, she should have no problem slipping right in there!
I tried that on my wife once, and I've still got the scars....

If you have 4-bolt mains and you are keeping pump gas compression with maximum RPM at or below 5500, you certainly don't need the mains doweled. I think my engine builder charges around $225 to install the dowell tubes and align bore. If your blocks have 2-bolt mains it is highly recommended you get them doweled especially before stroking.
