Dang it. Therein lies my current dilemma, too...
I've heard 1000rwhp is no problem for the LT4/LT5 stuff. But then I hear stuff like this, and I also want to take mine to the strip and launch it.
So while I'm staring at the back of my engine on the engine stand, I'm thinking, "What's another $2,200 at this point? I mean, it's right there looking at me and I have to install a flywheel and clutch anyway before the motor goes back in."
Back on topic, the LT1-S triple would be what I'd order on my car. I had one on my 5th gen ZL1, and it was awesome. A little bit of noise under 1500rpm, but otherwise you'd never know it wasn't stock (except that it never slipped

).
Let me know which way you go. Maybe we can get a 2-person group buy from Monster.
