camshaft?? Hey guys. Brand new here. Not totally new to camaros but new to upgrading them. Im gonna rebuild my 94 z28 soon and wanna do some upgrades. One of which is getting a better cam. So what is a good cam to put in it. Im not a drag racer and dont need that just a good cam to go into a near stock engine.

I bought the car not to long ago with low oil pressure. Guy said undersized bearings were accidently put it. So i gotta pull engine break it down and replace. And while i have it out ima replace a bunch of normal wear parts. Upgrade few things at the same time. Its at 200k so id rather put it newstuff now. All new gaskets and what not

if in fact "undersize" bearings were put in and now resulting in low oil pressure....wow.
have a qualified machine shop inspect/mic block, crank, rods, pistons/rings. sounds like you need a complete rebuild once you get this deep
you are going to get into $ quick. Decide what you really want out of the car/motor and build the new motor accordingly. If keeping heads stock you will minimally need new valve springs. Cam cards note min. valve spring required
some off the shelf cams used with stock heads are (need to get new valve springs):
Comp 502
Comp 465
Lingenfelter 211/219
or a custom grind cam from Lloyd Elliott or Advanced Induction
any cam will require a PCM tune
Given the unknown of what PO did to the motor...as Caprice notes you may be better off getting a junkyard un-molested LT-1 and "freshen" it up with bearings & rings.

Yeah possibly may end up getting diff motor. I just dont wanna go to deep into money. I just wanna open it all up inspect everything replace what needs to be and what not. Things im planning on replacing are:
Rods
Springs
Rockers
Valve lifters
All gaskets
Oil pump just because
Cam
Spark plugs
Wires
Distributor
Thermostat
Water pump
Thats the plan i just want all good decent parts. I want it to be good strong street car with little boost in power

Somebody is lying to you. Undersized bearings on a standard crank would be locked up. Would not have low oil pressure. Standard bearings on a crank ground for undersize bearings would not only have low oil pressure, but would knock so bad most people would not buy it after hearing it run.

Ive never delt with these bearing befre and do not know much of anything about them. Before i do this replacing i will be hooking up a mechanical text gauge to check it. But reguardless im gonna put buncha new stuff in engine. So you dont think it could be the bearing. He said the crankshaft is still stock

Likely does have the wrong bearing clearances, and / or a worn out oil pump.
Under sized bearings provide a smaller bore for the crank. If the crank has not been "turned", it would be too large for under size bearings. Simple.

When i start the car the pressure gauge reads about 30-40. After heating up to about 180 the pressure will drop to about 5 or less. So i dont know if gauge is lying. Maybe its the pump or some worn out clearences possibly. He says he replaced short block. Didnt ask why stupid me but i just want to figure the problem out. I know i can replace oil pump just by removing pan correct

Ed is right in what he says about the motor.
My comment above was basically to say if the previous owner was so dumb as to say such a thing, or to try and halfassed a shortblocks and still have low pressure etc, then I would just start over. Both he and you are too ignorant to do much but make problems worse, functioning used engine is the easy fix.

Don't mind "96capricemgr". He's not trying to be nasty and doesn't mean you're ignorant as in ill-mannered. I think he's just trying to say you don't have the knowledge needed to do the correct things required under the circumstances.
