I'd like to hear what Hughes has to say, they are a vendor on this site.
I used 2 Hughes solids in the late 90's early 2000 and didn't have a problem. I believe Engle was grinding them at that time
What say's Hughes ?
Howards grinds all the Hughes cams. If you look at a Howards grind that has the super fast rates the Hughes stuff does, they give you some warnings about them
I have a Howards solid that isn't one of the fast rate cams and it makes excellent power
