OOOOOO!!! OK I see. Just to recap...SO when I get my 240z I can swap an engine from any car into my 240z, as long as the engine is the same year as my 240z or newer. And the engine has to have all the factory smog control equipment (Cat,o2 etc) when I swap the engine into my 240z. If this is correct then I think I got it!
you guys are amazing!!!!! THANK YOU!
Good racing,
