I believe there is a formula for figuring all that out in one of my books...I will see if I can find it and post it tonight. The word "marriage" comes into play again in terms of your combination of parts.
I believe it relies a lot on your operating range (RPM) and cid...The unfortunate thing about all parts combinations is that there is only one RPM value where your setup will perform at peak efficiency. I guess this is a "non-answer" really...but an interesting topic. I'll see what I can find...

It's much easier to promise someone a "free" ride on the wagon than to urge them to pull it.
Luck occurs when preparation and opportunity converge.
