When good is not enough, Camshaft time again.

What is the best way to feed 512" enough air to be efficient and street drivable.
I don’t approach it that way.
I prefer to define the operating parameters and power/performance goals, then try to come up with what I feel is the best way to get there.
So, there is no one “best”.

With street cars it usually comes down to which things one places the most priority on, and which things are more “compromisable”.

Race cars are generally much easier overall, where the compromises are usually based around cost and maintenance.
