Here is the street roller cam going in. This cam is pretty close to the MP .590 in terms of 050 duration and lift. Specs on the cam are 260/266 at 050 and .588/.597 lift. The MP .590 is 265/265 and .590. But based on how these lobes look I've got to assume that this street roller has a ton more duration at .200 and .300. I'll measure it just to see.
