I have 113K on the engine. I have always been disappointed with the power. I suppose the 2.73’s have some to do with that. I was going to just put in a 125 shot of nitrous. But now I may have the money to get a Supercharger. Has anyone ever put a SC on a LT1 with over 100K on it? I was looking into the STS Turbo system but there is no way I can see to get the air tube to the intake because I have LT’s on.
I would hate to spend that kind of money only to get a few thousand miles out of it. I’m hoping to get some experience from those who have gone before me.

 

10.5.1 compression and a car that has been beat on for 113k would not be ideal for boost(not saying yours, f-bodies in general). It may last if you tune it well and do all the research how how to keep it alive, but it is going to die. You stated that you don't want to just blow it up, so the boost idea is not for you.
My advice is going with the juice at your point. Many guys here have high miles and hit 125,150,175 decent amounts and have no problems. I have 92k and after headers that is my next purchase. Read up in the n20 section for a while, you'll get some ideas.

 

Why not use the supercharger mooney and rebuild your motor? Go 355 or even 383.
