Rods hitting windage tray?
What would the symptoms of the rods hitting the windage tray be? I'm trying to chase down some problems with my latest build and want to narrow it down. I have a 4.125 stroke crank and clearanced the tray but it has always been in the back of my mind if I clearanced it enough.
My power is dropping off at 5800 everytime. It seems like valvefloat but it shouldn't be with my softer cam lobes. My other thoughts are that with my high volume oil pump, ls7 lifters, oil restricting pushrods and 20w50 oil that I am getting lifter pump up.

Ticking or knocking sound that varies with RPM. You can usually narrow it down to the bottom end by crawling under the car with it running on jackstands, and might even be able to feel it if it's bad enough. Have you checked your oil to see if you've got a bunch of metal shavings in it?

I can't hear anything at idle. I'm just wondering if it doesn't hit until higher RPM's. I haven't noticed metal shavings after the 1st change. But it's about time for another oil change so i will check again very soon.

Peace of mind is worth its weight in gold. A $55 windage tray designed for large cranks is what should be in that engine to begin with, not a hackjob modified tray, especially if the op has any second thoughts. Power dropoff? Strange noise? Hello windage tray not working properly

I run 5-30 in mine. Idle is 25 psi at 850 rpm with oil temps 195-205 WOT is 105-95 with same oil temps. cruse is 65
My mains are .002 rods .0025 alum block
The thick oil takes longer to get thru the engine, return to the pan
I would try some 10-30 and see what it looks like. You can always drain a little out and add some thicker to it.

If the crank was hitting the tray you would have noticed rite away when you were putting the engine together, while turning it on the engine stand. the power dropping off... small cam will do it with the kind of stroke you have, it would just quit making power, now if the valve float was present, is different, it will sound similar to hitting the limiter, but a bit more dangerous...

Cam is a 243/247 with AFR 230v2's. So it's not real small, but not a big cam either.
