This is a LT GenV engine that was removed by the Petaluma Chevtolet dealership. This is the improved version of the classic Chevy LS engine. The engine was in a 2015 Z71 Silverado. The engine had a #7 cylinder lifter collapse. the truck was repaired under warranty. 3 months later #3 cylinder did the same thing. The dealership replaced the lifter again under warranty but this time the dealership was able to order a new engine due to recall. The truck was driven daily over 3 months until the new engine was installed. This engine was removed with 105k miles. The engine ran perfect when removed. I was going to do the AFM/DOD lifter/cam upgrade. The stock engine is around 405hp. With the cam/lifter upgrade the lifter problem would be completely eliminated and HP Wwould be increased to over 450hp. My plan was to put this engine in a Datsun 240z. This engine is overkill for the application. i have another engine for the project so i no longer need this one. I will include an intake/throttle body with the engine. ($600 value), stock engine mounts, and engine stand/skates($100) to make it easy to move around. i have an engine hoist to load the engine. call or txt is good two O9 six zero two O8oneO
