273 Crankshaft

OK... the car is a 1965 dodge dart gt. 273cid. 4spd. 2 bbl. The car is all original, numbers matching...
Somebody will say it anyway so I will be the first: The engine may be original to the car but it is not "numbers matching" That didn't start until sometime in 1968.
69's had vin's stamped in the blocks.
