Speedmaster intake porting. Hopefully I can make something out of this

Ok a couple days of thinking and planning paid off. This mod was to the plenum only and required some time and grinding to accomplish. During the process you are basically improving two runners at the same time. I did grind through to another runner so I have a pretty easy repair ahead of me when I have my welder set up for aluminum. Now I know where to stop on the other side. I know what it needs for further progress but being Ethan is running a smaller cam and I would never run this intake it would be time wasted. I will let the cat out of the bag on this mod at a later date after I can explain how to safely do it. Today’s flow numbers are all on the same runner to show improvements in flow
