A guy is selling an engine in my local paper and i was wondering if you all could help me figure out what it is exactly it is. i don't know to much about these newer motors so your help is greatly appreciated. The guy doesn't know much about the motor either except that it came out of a 2000 chevy Z71 P/U and its a 5.7L long block for $400. i plan to build an engine to put in a mustang and run a drag radial class at one my local tracks. it will be boosted or have a healthy shot of nitrous. thanks in advance

 

^^^^unless somebody already bored it out it is a 5.3....roughly 326ci.
