Just wondering how long everyones lt1 lasted before they had to rebuild it? I've got a 145k on mine and still running strong.

88k miles, had a comp rocker nut come loose on me and let the valve hit the piston. I *might* have been able to save the motor as the piston only had a small nick in it, but I chose not to. My block is sitting in my garage awaiting a future build up after I decide to upgrade from my current 355 in several years.

Motor looked brand new inside.

What!?! Very strange, I've never heard of that before. Did you buy the car used or new?

Mine had 153K IIRC.

I still can't get over two people breaking the crank in half Other than extreme set ups I don't ever hear that happening.
