How long did your lt1 last?
 

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

141K, Times in sig in 90 degree weather

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.

101K - spun a rod bearing, 100% stock.

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

Mine had 153K IIRC.

122k and still strong, previsously supercharged before I bought it(X-75,000mi) zero blow-by(so far, LOL)

104K Had slight leak between #5 and 7 cylinders. Previous owner couldn't maintain a car if his life depended on it.

I am at 167k miles and it pulls just as hard as when i first got it a while back. mid 13's with the setup in sig

Re: How long did your lt1 last?

Re: How long did your lt1 last?
 

i drove it to high 13's bone stock at 133k...CAI and exhaust at 145k still running hard

Re: How long did your lt1 last?
 

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.
