Solid lifters or solid roller lifters?
If solid roller they should have a oil hole in the oil gallery into the bushing, .030 to .090 depending on the shop doing the work If not rollers no need for any other oiling
I need to go pickup my 400 block now after having bushings installed in it to seal the oil galleys up at max lift with the Comp Cams solid roller lifters set up for pushrod oiling, that shop put a .060 oil hole in the bushings I had assembled the motor and primed it and found out it only had 20 Lbs. of oil pressure with the comp lifters, I swapped them to a set of regular Cranes solid rollers I had in the cabinet and had zero oil pressure with them
This motor has a set of Jesel paired shaft rockers hence the need for pushrod oiling
Onwards and upwards
