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.
The thought of trying the performer rpm intake on your motor crossed my mind. It may make the same or a bit less hp, but the midrange just might offset the loss of top end more than enough to go quicker, especially if you have a street/strip converter with less than optimum stall. Either way, that motor will put a smile on your face.
