440 engine decoding

[70r/t440]

I have a 70 coronet r/t and would like some help decoding the info stamped on the pad on the top left side of the block. Thanks in advance for any help. As stamped:

F440
o
8 4 hp2

I know the F440 means 1970 440 engine block. HP2 i believe is a second shift build high performance engine. The other #'s i believe are date coding.

The 8 4 stamping indicates this engine was assembled on August 4th, 1969. So you must have a very early 70 model year Coronet. Probably has a build date of late August 69 or early September I'm guessing.

I agree with Chuck, the F440 designates a 70 model year 440 engine and the HP2 is also as Chuck said, Hi Performance version of the 440 and built on the 2nd shift.

The other stamping, either a zero or an "o", is not familiar to me and means nothing to me.


You should also have a partial VIN stamping on the lower passenger side of the block, just above the oil pan rail. It should be about 8 digits long starting with 0 (for 1970) then a letter (A,B,G,orE) for assembly plant, then the last 6 digits should match your cars VIN number. (This is assuming you have the original engine for the car.)

I appreciate the help from both of you. That zero in the middle of the info could be a backwards C also the more I look at it. So the stamping is:

F440
0 or O or a backward C (actually looks like a backward C)
8 4 hp2

Anyone else know what the middle line is? Thanks again
