Figured I would start this discussion here. I hope to actually expand this significantly onto the main site, but we have some work to do before then. Anyways, in my boredom (ok, not really..) I decided to try to draw up a 3100 cam lobe in CAD to help describe exactly how companies to regrinds to achieve more lift. So I mess around some and came up with the follow stock 3100 lobe:
Anyway, that is basically by just looking at it and going off the stock dimensions and specs I have. So its not exact. But, that won't be for long. Marty is in the process of degreeing a 3100 cam in 2º increments, so I will be able to draw a very accurate lobe. I also plan on taking the info and plotting the intake and exhaust lobes out in Excel so that we can visually see the profile, overlaps, LSA, etc... And after talking to Ben the other day, he is thinking about doing the same with the DOHC cams. Maybe I can convince Chris (or Marty again) to do it with the older motors as well.
Will be nice to finally get some info like this up on the site!
