Yes this is a new cam and lifters as well as the aftermarkert, stock style rockers, and factory pushrods from a 68 or later. As far a pumping up the lifter, this motor has never been started and the spring in the lifter is suffiecent to hold the rocker up (I have tried pulling up on the pushrod and the rocker does not move so I'm not sure what oil in the lifter would change as it would not hold pressure when the engine is off). I'm checking the lash with the motor not running. At this point I'm wondering if this motor may have had the heads or deck milled poorly at on time throwing the whole thing off. I'll look in this tonight. My question is still not answered as far as will this motor run correctlly with the .120 lash?
