422 dyno fail

Something is definitely a miss.
Cam installed advanced, straight up or retarded.
I know cam is hydraulic, but is the preload good?
Compression is a little low,but should have better results.
There is room for improvement with the carb and manifold.
I think hp should be easily in the 425 to 450 range and torque around high 4's.
What are the air/fuel numbers?
