About 10-12? years ago I could have bought a nearly complete ZL1 engine. It was stupid to not have bought it based on prices today, but I passed. It was $20k. If my memory is right it had the intake, correct dated heads, correct dated block, 7115 crank, dimple rods and standard pistons with an AS number stamped on the deck. No VIN and no engine plant assembly plant date and engine code stamping.
