DIY Engine Porting vid series!

(Admin feel free to move this thread to where it fits best.)
For those of you who want to pick up some power right at home, I'm putting a video series together on the tube, covering a lot of stuff the competition is tight lipped about. Doing a Briggs opposed twin in the series, but the rules apply to most other flatheads as well, OHV vids coming later.
I'm covering a lot of the 'why' as well as the 'how', and packing 35 years of experience into video form isnt easy- theyre long, drawn out and maybe boring at times, so grab a cup of coffee or a 6 pack and pull up a chair! This is the intro- watch em all!

I've been waiting for this for a while, will try the videos out, it's been a while since I've see a decent porting tutorial...

Awesome! Theres more than one way to skin a cat and nobody knows every little trick, so watching a bunch of different tutorials is probably a great idea!

Thanks for that! I agree with you, no matter how long we work at something, we never know it all. I like to watch lots of different points of view, with real experience leading the pack.
Thanks again!

Update:

After starting your video, I subscribed. I was happy to see the gray beard and the steady video.
No dramamine required!

@Nevadablue, yeah nice steady videos and very informative.

Dont worry, it gets worse hahaha

Gotta say, I really like your "DIY" flowbench. Quite creative, making essentially a manometer to compare flow readings while working ports.

Thanks buddy! Wish there was a way to calculate actual CFM, but its still better than taking a shot in the dark. HIGHLY recommend folks build one, dont think it took 10 bucks in materials and a half hour haha.
It has proven to be very repeatable with two things in mind: 1- run a baseline each time you do a work session- the numbers change a slight bit from day to day (likely temp and weather), and 2- once in a while it will give a really weird 'number' as much as a full point different than it was. I think thats shop vac rpm related. I just walk away for a few minutes and let it cool down and re run the test, appears fine.
