should have done bushings not bearings

Right, because the drip-drip-drip of oil metered up through the pushrods is splash lube exactly the same as the oil-everywhere constantly churned up inside the crankcase and slung off the crank's rod throws directly onto the underside of the piston is splash lube. I sure don't see any difference in those now that I think about it, thanks for pointing it out.

It's still not pressurized and just coats parts. The volume of oil slung around doesn't affect how much is forced between metal. It's surface finish, tolerances, movement, and viscosity. All the bushings have to do is stay wet. If there's enough oil for the trunnion bearings then there's enough for the bushings. The good bushing kits have oil grooves.

Where volume matters for splash lube is cooling.

Those needle bearing trunnions belong in the trash.

I'm still not getting it. Tens of millions of OE parts out there running billions of combined miles.

Brian Tooley does more Spintron testing than probably the combined rest of the aftermarket, and they have purposely chosen to go with needle bearings over bushings.

Tell us what you know that they don't.

I run bushings. You don't have to if you don't want to. It's not like I make a commission off the things.

I mean BTR sells plenty of cams for Gen III over .551 lift. We all know that the valve tips start to wipe and valve guides wear at that point. Nothing to argue about. Just consequences and facts. I know I won't have any blown out trunnions anymore. That's enough for me.

I had a set of bushings(Smith Bros?) wear almost immediately in a 6.0 with stage 3 btr truck cam .553 lift and matching springs. Maybe 6k miles-ish the bushings were wore completely through on nearly half the rockers. I bought a new-used set of rockers and installed the v2 btr kit probably 20k ago. Probably should check them as i have some valvetrain noise and quite a bit of glitter on the magnet at 3k oil change.

that is the reason i even checked my BTR upgraded rockers because of excessive noise which i thought was due to installing solid motor mounts from ssonly website. you see i recently posted a thread concerning a set of circuitwerks 2 inch headers which i heavily modified for my chevy ss sedan and my problem was that the header rubbed against the frame when under heavy acceleration so i figured id just put the solid mounts on and keep the engine still and the rubbing will go away. well it worked but then i could hear EVERYTHING including the whole rotating assembly with the solid mounts no bushings. my wife and i drove to laughlin to eat at bubbagumps and the valvetrain noise was horrible. the next day is when i decided to pull off the passenger side valve cover and discovered a crooked rocker. since then i have installed the CHE bushings and am waiting for the stock hydraulic motor mounts because as it turned out the original mounts were broken allowing the headers to rub in the first place. i could just bush the solid mounts but im thinking the stocks are hydraulic to keep the vibration to a minimum and i dont want to take a chance of hearing the engine droning in the cabin like it was. Anyways i know this is not about "tuning" but i want to thank everyone for their input

by the way i have been running the engine for 3 days with about 20 needle bearings unaccounted for and have not had any issue and the filter element had the same amount of trash as it always has so im not gonna worry
