Again, most will say the tunnel ram is for mid-to-upper RPM's but from your dyno sheet, this does not seem to be the case. It seems to peak at a perfect RPM for a street engine.

I am going more for the period look with my set-up, using velocity stacks topped with a Hilborn style scoop.

Another thing I see. You have the finned valve covers. Make sure you have breathers. I see the oil fill cap, and assume a breather on the other side? I also have finned valve covers and will be using the Moon add-on breathers ala the old school look. I mocked them up on an engine I have sitting and will mount the breathers permanent when I have the tunnel ram in place on the engine.
I don't have numbers from idle up, but the car drives great. Crisp throttle response and lots of low and mid power. I do have a breather on the passenger side and PCV valve in the valley pan. Your set-up looks sweet! What's it going in?
