I didn't look on the summit website, I looked on lunati's website and catalog. They show a 285/305 street/strip cam with .465 lift. Summit has a typo in their catalog. That cam is probably pretty close to what I have though. I'm guessing I have an older version of that cam, possibly from the 70's? I've attached a picture of the stamping numbers. This website didn't give me that option on my original post.
