That is so very true Justin, but what also is true (from my experience of 30+ years of building strokers) is past a certain cylinder volume to port cross section, the VE will start to drop rapidly if there is insufficient runner volume to keep the (bigger stroker) hole filled. Even with equal or near equal flowbench numbers. and Especially with a carb you have to have adequate room to get both the air and the fuel volume past the intake valve to squeeze and burn it. Fuel (even in suspension) is a solid and still consumes Volume in the port, and (normally aspirated and for a given cross section and overall runner length/port volume) past a certain point you can only get so much of both in only so fast.

I bought the AW's to try them because the VE ( broad torque especially beyond the torque peak) more or less demonstrates this point.

The other funny thing about flow benches is they measure cubic feet per minute. On a running 8 cylinder engine any intake valve is closed for nearly 2/3'd of that minute, and for most the other roughly 20 seconds it is only partially open.
