Anyone running this cam "577"?? In a big bore S&S 106 ( was a 96)

 

It will get the job done. Its just another choice in the latest round of designer cams. You should add some info like exhaust choice,riding style, compression ratio.

more of an Andrews 54 with some added intake lift, I have used a few, they work well as do many other cam grinds with very similar specs. No magic sticks anywhere just a lot of good sticks when used as part of a great total combination.
