I would like to know the same!

Too many people who were born on third base actually believe they've hit a triple.

Yeah, I must say it was a little disheartening to not get the exact figures I was hoping for. While I didn't include it in my original post, I went back and tested the intake at .010 lash. Ended up getting a duration of around 270. Exhaust at .020 lash was about 260. I suppose, looking back on it, I might have set the lashes a tad loose. Tightened the rockers until there was a good drag with the feelers, but wasn't necessarily meticulous about it. Overall though, I was very careful about "quality control" during all stages of my testing.

After all this work on the car, I'm feeling pretty lazy. BUT, I do still have my car's original Slant sitting in the garage. It would be interesting to see what I'd get for results doing the same test. I just have to gather the motivation. I'm really sick of the garage right now!

Either way, I feel comfortable setting this cam at stock lash. There's clearly a .010" difference in the height of the intake and exhaust lobes, and they seem (from what I'm gathering) to be about the height of a stock cam. So at least my testing gives me confidence in that (unless anyone says otherwise).

If anyone has any non-stock theories, I'd love to hear 'em. Otherwise I will keep repeating to myself: "It's a stock cam... it's a stock cam.... it's a stock cam..."

I just pulled out my graph. According to the data on the graph, 244 degree duration would occur at ROUGHLY .022" for both Intake and Exhaust. Granted, this graph itself is ROUGH, it is not very precise. I connected the dots by hand, not with a ruler. I created it simply to have a visual comprehension of what I was doing. BUT, I've got all the numbers. Are there any free cam mapping programs out there?

Again, the graph was created from data recorded from the valve retainer, rockers at ZERO lash.

Put it into an excel spreadsheet and then graph the results using the XY (scatter) that connects the dots with curved lines.
