This is all about personal preference, i.e. whatever floats your boat, and everyone will have their own opinion. We have folks on here with rotary powered cars, V8s, V6's, inline sixes, and the list goes on. Like I've said before, it's your car, and your money---build what you want. I have had Datsuns over the years with JDM power, and American power. I have left the Datsun emblems on, and they are registered as a Datsun. Don't be afraid to build your Datsun to your own taste, whether it's been modified, or left stock.
