Small Hughes cam in 318

I think the advertised number of 61* is on the mark. The United Engine calculator requires you add 15* to the .050" duration to calculate. So with that in mind, that .61* would equate to 46* @ .050. Sounds right to me.

It's easy to get confused using advertised duration numbers. That's why I never use it. I don't ignore it, it's just "not as important" when trying to calculate other specs.
