Jon Schmidt Video cam rebuff

Post by David Vizard »

Hey guys - it's been a long time since I have been here but work overload and ill health have stolen so much of my time - -

Anyway I am sure most of you are aware that I now have a very active Youtube channel at 'David Vizard Performance' Check it out - it's climbing the subscription ladder fast.

One of my soon to be published video's is the last debate that John Schmidt and I had on cam events vs cam dynamics - which was the most important.

I found John a very difficult person to debate so I have decided to do a video on just this subject to show conclusively HE WAS WSRONG.

JOHN - ANY PROBLEMS WITH THIS?????
A SIMPLE YES OR NO WILL DO.

Guys'
I don't think Jon has seen this yet. Maybe I should post in the general section!

Watching for the Video.
Ignorance leads to confidence more often than knowledge does.
Nah, I'm not leaving myself out of the ignorant brigade....at times.

Gary,
Sorry you saw it as that but this guy is dishing out BS and I know for a fact that neither of us like that.
How about you reserve final judgement until you have seen part 2 on Monday the 12 at 4 pm.

that 128 chart will get you close I'm sure for a chevy small block muscle car rough idle catalog cam. Simulation is better of course so you can design for engine characteristics. For a set of heads on a given bore and stroke you really get to decide what you want the power to be like. Truly enjoyed your cyliner head book, was fun to read about my employers
