A different kind of 400 build

[GenXCharger]

Hey everyone. I came across this forum and am glad I did...lots of good info. Here's what I'm working on and my goal. I'm restifying a 71 Charger 500 which now, or will soon have a 400. I am wanting the best compromise I can get between power and economy. The 400 has a mostly stock rebuild except an Eddy Performer cam. I also have headers, dual 2 1/4 with Dynomax Super Turbos, a thermoquad, Offy dual plane intake, 902 smogger heads and electric fan. With an automatic and 2.73 gears what kind of power and fuel economy should I expect? I'm not looking to have a road burner, rather something fun to drive and that I can afford to drive. With any luck I'm hoping to get the engine and tranny back in within the next month or two. Thanks.
