Bunkie314 Yes there are some people who drive very normal. You are right about a once a year check for lash on the valve train. Motors the at run hard bounced off MSD limiters,road raced and autocrossed, they need more maintainance and adjustment. Your cam is not that big. Now if you where running something in the .700" class and an Alum block and heads,you need to be checking. Pushrods geometery is a problem with the FE manifolds. There is alot of movement on the FE manifold. No pins or locators to make sure that the manifold is centered. I spend 2 hours grinding on my manifold for clearance of the pushrods. I do think that adding a .010
oil groove in the lifter bore to leak down to the contact point of the cam and lifter would not hurt. Scrapers and windage trays cut down on
oil spray in the bottom of the motor. This could be another reason for failures in motors. Are you running a HV-HP
oil pump in your motor? What pressures, hot and cold? Rick L.
