Some M1 porting pictures and flow numbers

Looks pretty good John, do you think if the top was squared to 4150, would it help it in anyway or not at all ?

Ok as i sometimes do I’m going to change up my answer to this question after sleeping on it. My head is always leaning towards the drag strip because that’s my thing but here we have a factory engineered intake that was made especially for the Thermaquad carb. With the small primaries and large secondary plates it was designed to help fuel economy, part throttle performance, and still perform well which after playing with one I think they accomplished. Did it beat out a modified Victor340??? On the street with the carb it was designed for yes I think it did. What other intake that is out there shined like this one out of the box.
