This is the UD cam I use in my 400, seems lively everywhere and pulls off idle through 5500. Idle is a little smoother than I wanted. The butler cam seems similar with a little less lift but more .050 seat time. Does anyone have the cam card for that butler cam?
This cam here would work great as it will create more compression with
It's low overlap. From the card I read it was 11* degree's of overlap.

Camshaft Machine Company, I am fairly sure still grinds the Wolverine Camshaft profiles.
I might still have a 744 High Lift Wolverine Cam on the shelf. Are you interested?

The Butler cam has 56 degrees overlap and the UD cam has 54 degrees.


Use Advertised Duration Numbers

When duration is increased and LSA is constant, the valve overlap is increased. When overlap is increased, vacuum is lower, cylinder pressure is reduced.
