Based on what I was reading in this section I'm sure you or one of the other guys can answer this basic engine yr vs model yr question in a flash...
If you have a car, say 1970, that was built Sept-Dec of the prior yr (1969).... Exactly what would be stamped on the top engine pad E440(69) or F440(70)???
The only # matching cars I had & ever cared to look at... were all assembled at the begining of the calander yr Feb-April and the motor matched the model yr. However my 70 6pack Road Runner was built 10/23/69 and the motor was long gone when I got it in 86 [raced most of it's life... One of many I suspect that were found at local race tracks (like Englishtown) with "MIGHTY MOPAR" or something similar on the side]
I put a 70 F440 HP six pack motor in it that came out of a wrecked RT Challenger. The ribbed block was cast in Nov 69(9 looks pretty close to an 8) & assembled in Jan 70. I have always wondered if I should be looking for one that is E440 assembled in early Oct 69... and would such a motor have the externally balanced crank & six pack rods or be built without, more like the A12 cars?
Or should 440/383 motors built in late 69 for 70 cars still have an F code instead of an E to match the model year?
