You would need to approximate the downstream restriction to get the flow rate correct. Also, you want to accurately model the flow split between the block and the pump bypass. Otherwise, running the pump could generate misleading results.
Here's a thought: build a motor mockup using a junk block and crank but with correct bearing clearances, lifters, restrictors, block passages, connecting rods, etc. Make a special shaft and adapter(s) to mount a C-face electric motor, driving into the distributor pad. You would need a variable speed motor that can run up to 4000 rpm (equivalent to 8000 rpm engine speed).
Then you could do accurate comparisons of pumps, pickups and pans in their installed condition.
FWIW,
Eric
