Not Ranked
The only reason I started looking into it was transaxle limitation that demanded a high revving motor. Then, I learned of some 40 owners with 8bbl injection, 331 inch motors, and throttle bodies that were only 36mm. The owners said the motor fell over at 5000 RPM and didn't do as well as they should. Once some of these guys went to larger throttle bodies the power came on and came on strong.
I know the formulas are an approximation, and certainly not 100% accurate. But I bet you can use much larger chokes, pick up some top end poke, and not lose anything on the midrange. I'm sure a lot will depend on your intake runner volume, cam, valve sizes etc but as a rule of thumb it might not be a bad approximation to use the formulas. Only thing is it is such a pain to go through and have to change them all around for new chokes.
I'd be interested to see how she progresses, but it sound like a strong combination already!!!!
