Head flow and power differences question / discussion

Sorry, the cam will be a custom ground solid roller. My builder had one made last year for my current 340 stock stroke. The cam guy took all the details, including altitude (5000’) and gave me a cam card and cam that made 400hp / 400 tq with a airgap and a Holley 650. This was only dynoed for break in not tuned for max power.
I am running a Edelbrock tunnel ram with two 660 center squirters.
The cam was designed for the tunnel ram.
Dude! You rock! Twin center squirters on a street tunnel ram, dang! That’s awesome.
If I were looking for 600hp I’d run the Indy set up. My view may be skewed though.
LMAO - “Skewed!” LOL! I like your car.
