I had a Charger with a .030 over 383, 906 heads with 3angle, with 484 cam, 750 VS Holley,Performer intake, 10:1 compression, headers, 2800 stall, 4.10 gears, 28"tires, 10 inches of vacuum. That car would absolutely haul buddy!
That's real close to this build except yours was 57 cubes smaller so this one should run good too.
If the compression test turns out fine I'd have to say something is up with the carb or lack of fuel. I ran a Holley electric pump with regulator to keep the fuel flowing for the motor. Other than that I'd say more stall and gears. Didn't really answer any questions but I know the motor ran very well.
