Andy, what sort of idle vacuum would you expect from the .528 cam in a 493? And would you install it straight up?

With the 509, it idles at a whopping 8 - 8.5 in hg. I'd like to see that improve just a bit.

Thanks!


Here is a cam article I wrote a few years back. Any of these cams would work fairly well in your engine. I think I have a few of these cams still sitting on the shelf. The Racer Brown cam for sure and maybe the Comp.
