Here is what I have...

1970 Challenger 440 Sixpack. build 0613


I am 90% sure the engine in my 70 440+6 challenger is original.

However, I have an anomaly that I have not seen before.

1. The casting number and date on the block seem correct for my build date.
2. The machined upper stamp pad has F440 HP and a stamped date of 0601,
the machine marks look very correct and 99% sure not been restamped.

now what is very weird.
The side pad is not been stamped with the VIN. It has the swirls that look very correct and thats it.

every other part on/in the engine compartment is date and part# correct.
Only parts that are reproduction are the coil and voltage regulator.
and they are dated/ink stamp correctly.



Is it possible that the engine got missed during the stamping process?

The 727 is stamped and original to the car.


I have just never seen this before. There are so many things correct on the car.

Opinions very welcomed.

FWIW... I was never told it to be original when I purchased the car. but the owner could not say either.
