for example my block has casting date of 7/70 was assembled 11/70 and did not go into the car till 4/2/71. since it was assembled 11/70 its orange but went into the car when most were getting blue engines. Not much set in stone with Chrysler!

I have a 71 340 block that was cast in Feb 71 and it went into a 72 car - so I doubt that your motor was in a 72.

Check the VIN pad

That's interesting. Is yours a '70 spec or '71? Weren't they lower compression in '71, or maybe that was '72.

Do you mean its most likely mine went into a 72, rather than you doubt it went into a '72? Your block was cast earlier than mine.

Thanks guys

Also curious, what do the first two digits on the VIN ID pad signify?

I've got one that's 0B, and one block that's 2B

Thanks,

Steve

0B = 1970 Hamtramck
2B = 1972 Hamtramck

Basically Year then plant the motor was installed at
