Hello,

New to this forum. Want to say thanks for all the gret information i have gathered off of here. I currently have a jeep wrangler im building for my wife to sand drag with, (300ft) Im running rear 9 in, th350 trans brake, 3800 stall, and have a nitrous lt1 currently installed. I just picked up a (i think) LM7 Came off a 2007 silverado with flex fuel and 243 heads with the triangle markings. The tensioner let go so i have to replace pistons intake valves and lifters. Im shooting for around 600hp w/ turbo. Planning on a 76mm. I will use the search button but will prob be asking alot of questions throughout the build. I work as a technician at a GM store in michigan. Tonight i will post some pics up of the jeep just to give you an idea, finding time for me is the hardest thing to do to be able to work on toys.

Thanks Adam

Welcome! What exactly happened that blew your motor now??

 

welcome to the forum

 

Welcome, any pics?

 

Timing chain tensioner, broke in half, took a ride around the crank gear timing chain got slack and whap whap whap went the valves into the pistons.

 

I read tensioner and was wondering how one would figure a belt tensioner would cause a piston to let loose... lol

 

Haha sorry should have been a little more specific
