Hemi fitment issues in 68 dart?

That's what I am thinking also. The engine builders seem to prefer the external oiling but again I suspect they want to make sure they never see the engine again once it leaves the shop. Actually makes sense from their point of view. Truth of the matter is this car if it does come to fruition will see very few miles, mostly ending up as a garage queen much like my 64 Savoy. Sad, but reality I fear. Thanks for your replies as they help me in my decision making process.
