for the fun I like your baseline carb Demon RS next pick would be the Holley ultra hp/xp
688hp 652 torque on the demon baseline carb
705hp 667 torque on the Holley ultra
you mentioned 93 octane fuel my engine program shows that it needs more octane, at least 105
And if you have time it shows that it might like the cam installed heads up at 108, instead of advanced to 104.
The ramp rate the dyno guy pulls the engine at will affect the HP numbers as well. I used 600rpm per second ramp rate for the pull.
FYI if he is using the latest version of windyn, it has an inertia correction factor, if set right, the sweep rate will not mater, 600 rpm vs 300 rpm vs step will lay right over the top of each other.
Explanation: the inertia correction factor is used to correct for the loss of torque as you accelerate the engine internals and related dyno equipment that is connected to the crankshaft. Without this correction you will get different torque reading @ each sweep rate.
