Old School 340 Build

I got that it's a leftover deal and I'm good with it. But when the food has mold on it, you gotta throw that stuff out.

As an example, that cam is 17 degrees BIGGER advertised and 17 degrees SMALLER than the cam I run.

That lobe was slooooooooooooow when it was first developed. I think that, all by itself, is a giant power killer.
I cheated...I had to look it up.
