cubic inches vs. head flow vs. rpm

that's a much louder bang than I am anticipating. were you ever to Oswego IL to race? my education and thoughts of how a car should be built is stuck in that era. along with the amount of money I have to spend on the car. your reply is certainly valid but 10K would be the very upper end if not over the limit of this budget. unless you know somebody who wants a hydrocarbon gas analyzer for $$$. my hope was to gain understanding in how to decide/pick parts.
