I need the compression rates for 84-89 3000 V-6 engines. I'm not sure wether they varied or not. I'm buying an 85 standard 300 ZX and my dad insists on finding out the Compression rate test and making sure it's within 5-10 pounds on every cylinder. The reason why I ask 84-89, is the previous owner punch a rod through the side of the block and the engine has been replaced, sort of broke at the moment so I didn't want to waste there time asking questions that were irrelevant. So in other words.. not sure what year 3000 engine is in there. Any help is appreciated.
