ZRP rods any good?

they all look to have a radial oil groove in the little end?...

so the oil shoots up the rifle drilled hole to the little end, bypasses the little end by taking advantage of the path of least resistance through that groove and then ****** out of the top hole giving light relief to the underside of the pistons; which are already being cooled by the oil squirters? Basically the oil isn't under enough pressure to form a full high pressured fluid film over the journal bearing of the wrist pin.

that's how I understand it anyway but I know others argue differently

@badger5

agreed
flawed small end lube design imho

personally, yeah; tried and tested. Bill stocks them...
