Magnum Cam recommendation

Dan Stratton said
If you take the MOPAR magnum roller lifter and the lunati roller lifter and put them side by side you will see the oil feed hole in the lifters are in a different location
I tried to use the lunati roller lifters and the rockers never got oil to them but I had good oil pressure still then I switched to MOPAR performance lifters and it works fine and have oil to rockers

also if you use the lunati cam it is actually made for the la engine and the snout of the cam is to long to bolt the timing gear on tight so you have to use the fuel pump centric from the la engine to take up that clearance so you can tighten the cam gear
