I ran into this last night in search of the formula to determine what is the best size venturi to suit a shared plenum intake (I came up bust but I did find out a lot of other useful info). This might have a link posted somewhere else but I'll chuck it in here - http://www.fordfe.info/CarbMythFact.html
The observations made in regards to carburettion aren't specific to an engine type or carb (he uses 2BBL vs 4BBL for comparisons of CFM) but if you're an engine NERD and are interested in the formulas to calculate ball park fuel delivery tuning then this will be very helpful.

He then goes onto header design and how that has a direct correlation to HP (air in - air out) and I know there are guys here who are onto R&D of their own headers so I also checked this out - http://www.superstreetonline.com/how...m-made-header/
(this went straight over my head - me and algebra are not good buddies) If I had the skills and time I would be all over this!
