It is a Lightning Block, bored .30 over with a set of custom Diamond pistons and rings for a 10:1 compression. I wanted more power out of the motor with less boost. Forged H beam rods, and a polished Lightning Crank. This shortblock has ZERO miles, and is brand new. Done right decked, honed with torque plates, etc.. I am asking 2000.00 shipped. I bought this from Lynn Chambers, I believe he resides in Georgia. I bought it from him. He is under the screen name orange2004cobra. It sat at SVC for the swap but then things went to hell financially that prevented me to finish the swap. Now it just sits in the garage since SVC is no longer. I need to move this so I am able to keep the truck.
