LBZ cracking pistons?
I've been reading around the internet that lbz will crack pistons under high hp ratings 500+ but I've also heard of them cracking under stock performance. How worried should I be about cracking a piston just keeping it stock or even if I add a little power with efi live. And if I do crack a piston does anyone have any idea on what that would be price wise to fix it or would it be cheaper to put a reman motor with a warranty in.

Don't worry about cracking a piston, i've got 130k miles on my truck and havn't had an issue yet with pistons, been running a tune for about 40k miles:tu:

Have you ever had any problems with your lbz I bought an 06 lbz just a few months ago for my first truck :jump: and im just trying to see what ppl had problems with them:c:

Haven't had a single issue with mine! 224,463kms strong. Dyno'd 530hp and 1092torque!! Been running that tune in my truck for 2 years.
The only way your going to crack a piston is if u keep your foot in it for long periods of time. To high egts for to long. Keep an eye on egts with a gauge and you'll be fine. Short bursts of high heat will not kill it. |

LBZ's don't really have any issues. Pistons are the weak link if you start making big power. I've seen lots last at 600+ hp. Driving style has a big effect on how long they last at what power. I guess with a stock truck, if you kept it pegged every second you drove it, they might fail sooner than later...Or if you have a 600 Hp truck that you drove nicely, it would probably last a long time.
