although you didn't say why... we ALL ASSUME you also came up with the correct answer

Did you get a chance to read the ramtheory link? What I'm trying to do is back up the cams peak torque, by attempting to time the intake wave oscillations so that @ 5500 as the cam begins to come on its peak, I can add a bit of ram theory to better maximize that rpm band....

VERY simplified - because the valves open and close the intake charge is actually moving back and forth, or more accurately a pressure wave is moving back and forth inside the intake and the port. What I'm attempting to do is either add, or subtract the .9" of the delete plate to better match the intake length to the desired peak torque point (or as close as possible).

Shorter isn't always better.....

If I did the math correctly, you want to leave the TVIS delete in for the ideal runner length of ~11.65". With that length the pressure wave would travel the length of the runner exactly 8 times from intake valve opening to intake valve opening for maximum ram effect @5500 rpm.

that's the theory....
