Advanced 4 degrees. It should give you the timing events on the cam card

Richard,

i'm dying to know how that cam performs.

I was considering that very one as well as 401A4Lun

har far are you away from taking that Z out?

Thanks

Aaron

I hate to say it but its going to be a while.The carbs for cross ram wont be ready for another 2-3 months.If you call Lunati,they can grind you one and you should have it within two weeks.

Harold help!
thanks Richard

svtrich,

I'd put that cam in anywhere from 105° ATDC to the 108° ATDC that it should be ground on. It will pull over a wide RPM-bandf with any of those settings. The 106° is my favorite.
You can run the valve lash as tight as .016"/.018" hot.
Let me know if you need more info, but I'll answer tomorrow, 'cause now it's off to bed....
