High capasity oil pan
#3
Why would you need it? The oiling issues on gen III blocks wouldn't be fixed by a larger capacity pan...
At most for the street, get a larger volume oil pump like the LS6 and clean it up (port it by hand or buy a ported one). Even then, it's not going to fix the fact that GM feeds the valvetrain first on these blocks instead of the crank. The only way to fix that is to get one of the new blocks from World Products (they feed the mains/rod bearings first).
If you're going to road race it (where constant high RPM could cause cavitation), go with an aux external pump (like Accusump/etc), or dry sump it.

Well, I was thinking that with forced induction (crank case pressure), high rpm, and heat from the turbo. And the fact that the gen 3's oil the valve train first (ss bnoon ss thanks) I figured more oil makes for cooler oil in the motor. Cooler oil on the valve train could help with knock. I know that oil needs to be hot to lubercate well and to clean it self. But I think that heat from a normal motor and the heat from a FI motor may be alittle different. Turbos are going to heat the motor oil up alot more. I am not saying that the oil can't take it, I just think it does not need to be that hot. I would like to bring the motor oil down to normal heat. I know afew guys that road race there motors and have 10 quart oil pans. I figure the cooler cumbustion couldn't hurt. They say that heat is a big factor for knock. I would like to cool the oil. I could use oil coolers and filters to add more oil and cool, but I wanted info on biger oil pans. I do not pretend to be an expert on this at all, I am just thinking about my options. I was talking to another racer and he was saying that at high rpm's you are useing all the oil in the pan. I figured alittle more wouldn't hurt.
On my truck I am pushing the stock 5.3 as far as I can, just to see how far it will go. I have a 6.0 sitting in the garage that I will be building next, so I want to learn as much as I can on the 5.3. My oil preasure is high already, (60-80) I dont think I need the ls6 oil pump. I run 5-30 weight oil too. I'd be scared to see what it would look like with 50 weight.

Also, you mentioned your oil pressure and that you wouldn't need the LS6 pump... The LS6 pump is a larger volume pumpe. Larger volume has nothing to do with raising pressure, it just holds more oil inside it which would help avoid problems in the event of momentary cavitation at the pickup tube.
With an engine on the stand, get one of the LS6 pumps. It's just cheap insurance. Is it worth putting one on the stock engines? Well, perhaps if you're in there already swapping cams or something...
