Picture of 340/360 head porting....Mistakes?
Well, if the bowl is shaped like a funnel, that measurement would be pretty far away from the seat, and wouldn’t be what I considered the throat.
But I’m certainly not the last word on porting definitions.
To my way of thinking, the bowl and the throat are referencing different parts of the port....... even though they’re in close proximity to each other.
For example, I just updated some Indy EZ’s a couple of weeks ago.
I increased the intake bowl diameter...... but didn’t increase the throat diameter.
