Putting together a 413 for our '62 300 Sport. The car came with the 383, so the 413 block is from a '64 Imperial Limo.
The oil runs to the top end of the motor through galleys which travel through the rocker shafts.
I have all new rocker shafts, arms, lifters and pushrods.
The lifters have oil holes on their tops.
The pushrods have oil holes that run though their center shaft.
The rocker arms have oil holes in the dimple, where the pushrod seats.
Today I spun the oil pump to get the oil to the top end of the motor. And the lifters filled up first, then the oil traveled through the pushrods, through the rocker arms, which then flowed over the rocker arms and back down onto the head area.
I don't think the oil is traveling through the shafts and out the shaft oil holes, though the entire top end is getting oil.
Am I fine?
