According to the MP catalog;
Advertised duration 296/296
@.050 251/251
Lift w/1.5 rocker .557
Lash @ .028/.032
Centerline 110 w/76 over lap
Through out the years, the @.050 specs waver and I do not care to get into what others have found. Some say it’s bigger, some say it’s smaller.
I just say, run it with 1.6 rockers.
