Engine lifter or rocker noises after hard drifting
So I know these engines aren’t dry sump but went to a local Auto-X event on stock suspension, and ran several laps & after words did some drifting in a wet empty parking lot. Tires I just replaced 2 front with Bridgestone S-04’s 255/35ZR18. Still running the 275’s out in the back burning them out ready to upgrade to the Bridge RE-11’s 285/30ZR18’s. Anyways after I got home popped the hood and noticed my engine is making more noise. Cant tell if its all the lifters or rockers were starved of oil. May be out of my ball park but anyone have any idea what a custom dry sump oiling system would run on these wet motors?

I used to be involved with an oval track car, which used a dry sump system. Based on my experience with that type of pump (Aviaid 3 stage pump), I'd hazard a guess and say that the possibility of installing a dry sump system would be extremely difficult, due to the lack of real estate....

BTW to compensate for not having a dry sump what pump should I upgrade to? HP pump or just upgrade the spring in the stock pump?
Thanks guys.

Gm white spring is $4, but honestly you should be fine. If anything ask Sam strano, see if he has ever had any issues with the stock system in all his years of racing. I don't see how you'd need to do anything at your level, unless your pickup maybe fell off or is loose and swinging.

Check your pushrods to see if any of them are bent. Check the rockers to see if there is any damage on the tips. If you have roller tips (I can't remember if stock rockers do) check them to see if there are any flat spots. If there is an abnormal noise you shouldn't ignore it even if it goes away.

Kinda late now that u already have low oil press. Low oil press usually indicates bearing wear. But if your interested in oil control Canton has a couple of items that can help the LT1 F-body.
First is a road race oil pan: https://www.cantonracingproducts.com...-1-PIECE-SEAL/
Not cheap and u would have to pull the engine to get it on your car.
Second is an accumulator: http://www.accusump.com/accusump_units.html
These help fight low oil press and helps lube bearings before start up too.
U may have heard or these before but maybe not.
Good luck,

With your motors age and miles I would put money on it being bearing wear, especially if it started after running hard for an extended period of time.
I have two LT1s and both started showing low hot idle oil pressure, one at ~160k and the other at ~150k.
