Comp says must convert to a oil through pushrod system. What exactly am I looking at to make this conversion? 408 small block non-magnum block. Thanks!
Run an HV oil pump if you think volume is an issue. Most of the aftermarket LA lifters today have an oil hole in them. If the oil is already squirting out the lifter hole with ~75% of the time off the lobe in a solid lifter doing nothing but flooding the lifter valley, why would you not want to divert some of that oil up to the rockers 5 inches higher 25% of the time? Drain back is pretty good from the heads..as you got multiple 2" holes right back to the lifter valley. The lifters, are they called out as a magnum (fulcrum rockers) application? That would dictate oiling pushrods..Dunno, am I visualizing this wrong?Too much oil will go to the top end. You're asking for trouble if you do oil thru pushrods. But it's not my motor. Do what you want.
No sir I haven’t convinced myself of anything other than replacing the hydraulic roller with a solid roller. I’m hoping I can just re-use the shaft and rockers. Then purchase the cam, lifters, and correct length pushrods.Lots of other people will chime in. Pick the answer you like. You have convinced yourself already you want oil thru pushrods. So go with it. Right or worng?
