Here is my ***** about this honest & factual statement.
How many of these engines are running around today with there exact stock equipment AND are ready to be swapped in place a turd engine.

The the statement is an old stall one that no longer be argued or applied.
So where we really are is a place of what you want to build. Unless there is a Daddy Warbucks giving away vintage sealed replacement engines?
