I agree, there is nothing wrong with a diy flowbench for testing what modifications work and what one do not.
On the other hand I do agree that the std intake manifold can flow enough air for a 350 and maybe a 500 cfm carb to give noticeable bhp gains.
My theory that an inlet manifold should flow more air than the inlet ports and that the carb should flow more air than the inlet manifold stands true.
However I understand why Graham wants the carb to only flow as much as the manifold as fuel econemy is the name of the game with this engine he is currently building and all of the mods he has done to the manifold and carb will give a substantial improvement in torque and bhp.
