HELP figuring cam lift ( maybe actual purple shaft p/n?

[PRH]

I'm building a .060 383 for my 71 Demon. Mostly a street car that I'll likely take to the track a few times.

If you had to have a MP cam for that, and it had to be a SFT, and if they were still budget friendly(and actually available), that really sounds more like a place where a .528 cam would be a decent choice(as opposed to the .557).
I’d use the specs of one of those and look for something similar that’s readily available.

Man, I need to learn not to post with half a cup of coffee ingested... yes, sorry, the 528 is more in line. I'm likely going to sell this and contact Ken at Oregon Cams after I get the compression figured out.

That's the lifter angle and bad rocker geometry

It's a factory 1.5 rocker ratio, that's really closer to 1.45, or less.

Ken has a great .528 grind. I think it's actually .539 lift, but it's essentially the same cam.

Thanks Rusty. I do need to get off my *** and get this engine put together. lol.
