'89 roller-cam LA 360 w/Magnum heads - new roller lifters not pumping up

as a note..the 89-91 hydraulic lifter are not designed to oill thru the pushrods..the newer magnum roller are ...

I know most of what you can buy now are the magnum lifters that do oil thru pushrod...

This is what was in the engine when I got it. Pushrods were shorter than Magnums for the LA heads, of course:





While I don't deny that at least 8 lifters had been swapped out on this engine when I got it (or Mopar installed different batches on each side - wouldn't rule it our), I highly doubt that all 16 pushrods had been changed to oil-throughs. That, and prior to this year, that engine lived its life with it's factory TBI injection system inside a B350 high-top camper conversion. Probably the last vehicle on earth that would get modded, unless Roadkill had bought it.

That said, there's no reason the Magnum lifters shouldn't work - and I've already proven that oil does effectively get to the lifters.
