I am unaware of anyone else using Cam Master software from Mr. Vizard.

That is how I recall it. It was promoted in some of Vizards book as modern cam selection software. I know of one person that ordered from MM&S. It was a flat tappet and supposedly custom ground. It had tighter lobe sep than I've seen in typical shelf cam offering. At the time it was about $50. more than a comp shelf cam.

I know in Vizard's latest copy of "Small Blocks On a Budget", he makes a statement in there about having never lost a cam shoot-out with anyone in 30 years of dyno testing. That's a pretty bold statement and I trust that every bit of his knowledge is in that software program.

I'm not saying anything what-so-ever about Mike Jones and I plan on contacting him when the time comes, hopefully this winter. What I am saying is that the program is nothing like camquest that's going to spit out something that they already grind.

When I asked Denny about its parameters, he said it was designed to estimate the cam specs that would yield 100% VE (at least for the street/strip selection) for your given engine data at what ever torque peak you specified, IIRC. I haven't spoken with Denny since early 2004.

When I spoke with David I was told that the formulas used in the program are based on empirical data gathered from over 10,000 dyno tests.

That is a lot of dyno pulls. I wonder what sounds are in his head when he lays down to sleep :lol:

What would be interesting to know is if Mike has ever used Vizards program and does it recommend something usually in the ballpark of what he would. Obviously not to reveal any secrets, just a ballpark.

Comp Cams will spec your cam (theirs) with their CamQuest software.
CamQuest recommends the closest cam they have on the shelf! As long as your engine will work best with a 110 lda, #-o I guess you are good to go!

Everything I have learned has been from David’s books and the Cam Master program.

His new book
http://www.allbookstores.com/How-Build- ... 1932494846
has a chart in it that makes cam choices easy and precise, if you follow what the book teaches to the letter you can expect these kind of results.

Videos below are,

Getting it down the track is up to you.

Right about when I tried one of their bump-sticks! (BTW, it worked great until it broke into five pieces, thanks to a couple of errant con rods... #-o

Been there done that. :( This engine had a GK flat tappet that Gregg (who Harold replaced) had gotten for me.

I ran two GK cams back in the 80's that worked very well for what they were.
