Sad thing is, dirt aside, they missed the #1 silent killer of LA oil pressure: CAM BEARINGS. It's a real thing! They blamed the oil pump? That's rookie logic, like the ignition coil being "bad" when there is no spark. Then they said "lifter cup height" which they said is due to "AMC" lifters, which is really what we've been using for years in pretty much any aftermarket LA engine build. If the preload was off due to "thicker than stock shim, composite gaskets", they could have slipped some simple .080" common lash caps on the valve tips and got close to .060" effective pushrod "length" back. I posted the cam bearing theory and the lash cap advice on Lunar's, Nick's and UTG's live streams and regular video post comments, but instead they are buying different lifters (after the perfectly good "AMC" lifters are already mated to the cam) and a host of pushrod/rocker parts to blueprint the valvetrain on a BUDGET engine to get: OIL PRESSURE.
