how much does the LS1 like 4k - 5k RPM playtime?
a house we might rent is down a few roads that have no access roads, they kind of just go through a bunch of fields.
well i've discovered they're perfect for 3ed gear fun, keeps it right at about 4k - 5k rpm's
then i realized that keeping the LS1 at such a high RPM for extended periods of load might not be such a great thing.
how well does the LS1 hold up to 4k - 5k RPM playtime? when will i start to spin bearings?

as a one time thing the ls1 will hold up to 6.5 even 7k if the valve train is set up wright, since you'll probably **** that up before u trow a bearing, or that will casue u to trow a bearing.

4k-5k rpm is nothing for an LS1. You won't start to spin bearings unless you do that at over 7000 rpm. The Open Road Racing guys run them at 6K+ for extended periods. As mentioned above, it's better if there is a load on the engine. At light load and higher revs LS1's go through oil like cool aid because the piston rings flutter. So keep an eye on the oil level while you're doing that. Don't worry about wearing out the engine, you will get tired of driving that way long before you wear it out.

ORR engines don't last 100K miles, no question about that. Some of those guys change rod and crank bearings once every racing season. But that is what you get with any engine that is operated at close to full output for extended periods, unless the engine is tuned so it doesn't put out much power for it's displacement, like my '85 IROC. It had a 305 ci engine rated at 195 fwhp . . . and it still ran the same as new after 200,000+ miles, even with me driving it!
What he is talking about doing is not going to stress an LS1, though.

i do agree with u in that he wont be spinning any bearings anytime soon doing that but if he keeps at it every day the life of the engine will be significantly shortened.

the car is stock, so it won't be seeing past 4k - 5k for extended periods of time and it certainly will never see above stock rev limit.
i'd say total time at the sustained higher rpm's is like a minuite or so, like a couple of miles, nothing like road racing or anything. sometimes i go autocross but thats only like once every 4 months or so.
i realize that i'm beating on the car, i'm just not sure if its "too much" beating or am i going to be just fine?

Yep fun stuff; I drive a twisty road to work and back every day, and autoX once or twice a month. When I tore down my engine to port the heads, the only problem I saw was carbon accumulation from burning oil. These engines do consume a lot of oil at high rpm and light load.
