Johnny, I like you am the second owner of a very well maintained higher mile car. I read a Car Craft article a couple years ago were they bought a junk yard LT1 out of a taxi with 150k on it. They opened it up and the thing had no wear or taper in the bore, they honed it with new rings put a H/C on it and made 400hp.
Your engine could probably use some new valve springs, LT4s would work good for stockish mods. I would reccomend a new GM timing chain set too.
Get yourself some headers, gears and a performance mail order tune will wake up the old girl.
I'm also on the original clutch at 119k. I keep waiting for it to start slipping but I can still bark 3rd so knock on wood.
150k is the new 60k!

I always laugh at the comments of 150,000 miles isn't much. Like my one buddy that says his diesel '99 F250 that has 300,000 miles..."oh thats nothing". Yeah... 150,000 miles thats a lot bro. You should just replace the clutch since it's got so many miles on it -- get a Spec 2 they are very good and will last a long time. Put a heads/cam on it and spin it no higher than 6000RPM. 410rwhp will wake that thing up.
By the way, it may just be the way i drive...but I've been through 5 clutches in 30,000 miles, and 2 motors.

I run clutch components at 11,000rpm for 16,000 hrs between overhauls on machinery at work. Every 1hr they slip the clutch for 10 seconds. And on startup they slip the clutch for 200 seconds. I think your problems are elsewhere, if not your driving style, then the clutch hydraulics might not be properly adjusted, or oil getting on the friction surfaces.
