First question I'd have is: do you plan on taking this engine apart and rebuilding it or do you just want to add the flywheel, install and go?

You say the pulley arrangement is different but apparently the pulley's are all there. So what's the problem? Do you mean the water pump pulley and/or alternator pulley might be offset? Did the motor come with the alternator and water pump, alternator and water pump pullies?

Need more info...
