Big horsepower 318 builds

Here’s an example of the formulas not working out:
540” motor, heads flow 360.
Formulas say 740hp@6300.

Intake A 732hp@6400(pretty close)

Intake B 805hp@6800(hhhmmmm)

Intake C 848hp@7300(uh..... way off)

Tests done back to back, no other changes.

The problem with the formulas is...... not enough inputs.

Like I said previously........ if you built a 318 along the lines of what was in that video, it would be a slam dunk 500hp.
