I have no clue what banks is doing. I have heard that they run a good bit of squeeze which definitely helps with smoke control in addition to whatever engine internals they have.
I guess my point which I should have come out and said is that running an intake profile that closes the valve soon after BDC will capture a great deal of air at low rpm, create a lot of cylinder pressure and give great spoolup. THis kind of cam will not do as well above 4k though.
The flip side which I was hinting at is that higher compression ratio will help push the chargers a bit harder and give better spool. In this case you could run a larger intake profile that closes more degrees after BDC. THis would bleed off some of the cylinder pressure at lower rpm. As the piston is on it's upward travel while the intake valve is open, instead of starting to compress at low rpm it will be pushing air back into the runner. High compression would offset this effect and still give great bottom end spool. The benefit comes in that as RPM increases you can not adequately fill the cylinder so the larger intake lobe will in effect be able to capture more air as the rpm increases.
A lot of the pullers run large intake profiles that bleed of a lot of cylinder pressure at low rpm. Combine this type of cam profile with low compression, and it dictates ether be used to help create enough cylinder pressure at low rpm to fire. THese engines hardly run until rpm reaches the point that enough air is trapped to fill the cylinder and enough combustion gasses are present to light the chargers.
This is okay for pullers but not for street use. You can use high compression to either run a larger cam that in effect becomes more efficient as rpm increases or to light a bigger charger that will also run progressively better as rpm raises, but not so well at low rpm that it creates catastrophic cylinder pressures. I guess what I am saying is that if you run high compression, you wouldn't want a small , high torque cam and a 62/12/65. Cylinder pressures down the highway would be crazy. Bleed it off a little with a larger intake profile or run a larger charger so that you would'nt overspeed it by 1900 rpm.
Just some thoughts. Do not mean to disagree or negate what others are saying.
