Have you ever played around with some of the engine analyzers that out there. Dad and I use the Performance Trends Pro quite a bit. They are easy to use and can tell you quite a bit about engines.
The 20" tuned length may not be that hard to get, since the runner length starts at the carb throttle plate and ends at the valve face. Stock intakes are not that far off.
I decided to convert my two carb intake I am making in to a Quadra-jet four barrel intake. The Q-jet has small primary's and should work very well on a inline. The secondary air valve can be tighten up so as to not bog it down when opened, but still operate with decent performance.
