Those are good numbers for a pump gas street engine. If you thought you were building a race engine then you went way too small on the cam and the compression.

The 512 low deck in my '65 Coronet makes similar numbers. I use a hyd roller cam with 250 at 0.050 cam and 10:1 compression. I also have CNC ported Edelbrock heads and a Performer RPM intake with a 750 carb.
