Unhappy Gas guzzler

I've built and have been running a 64 Chev full size street machine. Car is totally debugged and runs great except... this thing drinks gas like it's going out of style. Some basic specs- 400 SB that is very well built but not running a lot of horsepower (Maybe 400-425), TH350 with 2800 converter, 3.55 gears, AC, etc. This is NOT a fire breathing dragon. Have a brand new Street Avenger carb on it as well.

I don't expect this thing to sip gas like a VW, but I've got friend running 700+ HP who get better mileage. I know 400SB's are not economy motors but 5-7 MPG is NUTS!

Open to any and all suggestions.


Let me add some more detailed specs as to the motor. 400SB 10:1 compression. Trick Flow heads with roller rockers. Edelbrock Performer cam and manifold. Holley Street Avenger 670CFM, headers. Moroso 9 quart pan and high volume pump. Accel ignition and distributor. This car is a total frame off and is literally a new automobile. Runs like Jack the Bear but drinks like WC Fields!
