Mopar ( Tube Kit ) info requested !

Good question. Is it needed for a solid cam?
IDK. I’ll be watching this thread. I have a NF lobe Ultradyn cam @ 272/.600+. I’d like to use it in a drag car set up I’m building up.

The tube kit mod is a oil restriction to the tappet. You would need to drill a hole in the peened tube @.060 or less.

It is easier to farm out the work but it can be done at home. You will need a drill long bit at least 1/2 the blocks length to drill the oil galley.

According to the MP books, for a roller cam it is required but I have not read (or remembered) it’s “need” for a solid lifter cam. To control the amount of oil that “bleeds” through the OE oil feed to the lifters, (A huge hole) this mod should be done.

Not that I’m an engine building pro at this level but I don’t see where it would hurt. I also gigue that a cam like this would have supporting parts like a deep pan and maybe a high volume oil pump.
