D4B DC mods like the LD340 DC mods?

How about a new AVS2 800 cfm with the D4B and a Racer Brown cam suited to the stock piston and 4 bbl automatic, 3.21 gear? I guess I'll ask Jim. I almost called today but I was driving and didn't remember till after 5pm Eastern.
The 19129 is factory refurbished and only $400 when they're available. I liked the 500 cfm AVS2 on a 318 smog motor I had.
AS far as the cam goes I'm looking to make the most of the stock compression. I get good gas here, real gas $2.95/gal. for 91. I just want this thing to be an average engine. Good to excellent fuel mileage. Mild street. Good vacuum. Easy on valvetrain. A cam that takes advantage of the Mopae lifter too.
