LS7 for sale @55k mile from 2007 C6 ZO6. Located in Massachusetts near Springfield.

LS7 motor was running strong right until the crank pulley started contacting the cross member in front of i due to known harmonic balancer failure.

A video shortly before the motor was removed, showing an average day at the track. The dashboard shows oil pressure, rpms, water temp and acceleration:

The motor is stock except for American Heritage rebuilt heads at @50k miles.

I have Blackstone oil reports for the past 6 years of my ownership of the car, including one from July 2021.

I have always used Amsoil Racing Oil.

I had a fresh motor built with some additional hp, using a complete core motor I purchased. So this will be a complete long block.

Latest oil report below

$8k or best reasonable offer.
