Cam gurus- Thoughts on the specs of this cam.

[Tim Ayers]

Some of you may know from my previous posts, I'm a cam nut. Not sure why camshafts fascinate me so much, but they do. I'm also slowly working towards designing my own cam, but that's a thread for another day.

I took a chance on this freshly ground cam on Ebay and I got it for a great price. It was ground on a super nice core.

What intrigued me was that that the exhaust & intake timing events seem to be similar to a Merc. cam, but this grind has much more duration and lift than the Merc.

Here are the specs at .050"

Intake opens: 10 degrees
Intake closes: 50 degrees
Exhaust closes: 10 degrees
Exhaust opens: 50 degrees

Duration is 240 degrees @ .050"
Lift is .380" I & E
110 degrees lobe separation.
20 degrees of overlap

Putting the specs into the Tilden Technology cam lobe data spreadsheet, it seems like it should be a fast action cam.


Curious on your thoughts.
