I have a 360 LA motor I built and It has a Hydraulic Lunati bracket master camshaft 480 lift. I used stock rockers on the shaft and comp cams self oiling push rods. I was getting on it pretty hard yesterday and 2 push rods shot through the rocker arms. I noticed a few others are cracked. I want to switch over to roller rockers. All of the shaft mount roller rockers use the cup style push rods. These rods are solid and no oil flows through them. Is this a problem? Will oil get to the top end of the motor if I switch over to the roller rockers and cupped push rods.

 

All LA engines are designed NOT to oil through the pushrods.

 

Are you using stock springs ??? I would suggest checking the springs for possible coil bind ? Or possible push rod length..

 

Mine is an early 80s engine and it oils through the push rods and the stock rockers have an oil hole where the push rod rests and oiling slots that allows the oil into the shaft through the holes on the bottom of the shaft. This is what has me puzzled. Roller rockers use the solid push rods. How does the oil get to the rockers if its not coming through the push rod?

 

How many bolts does the valve cover have ?? Could it be a Magnum 360 motor

 

no it is an LA engine 5 bolt holes in the valve cover

I hope this clears it up.
