318LA Myth's still being created!

I looked in my 1966 Plymouth parts book and the 273 and 318 Poly are the same crankshaft for that year. Probably sorted out by post #37.
As a replacement crank (2268119) for a manual transmission application, that's true....although I would still rebalance everything. For the automatic 273 with a 904, there is a different part number (2463551), and crank due to the difference in converter hole diameter. 273's in front of a 727, like what was in an A100 van, a police car, or taxi, would have the 318 crank. That doesn't matter on the manual trans applications since the outer diameter of the register hub is the same as 318 flywheels. (and others).
