I am looking at this date coded block for my car, it is 3 months earlier from the build date of the car.
I keep hearing conflicting theories on HP and HP2 440 blocks, some say they were merely shift differences, HP being day, HP2 being night. However my question is, why would CHrysler care about making a engine block stamping such as HP with a shift denotion?
I always get this question when people see my car, "Wow, does it have the original HP2 block?", I say no it has a HP, and they seem to think it is not correct for a V-code six packer.
Any true V-code owners attest to the fact they have a HP block or is it all HP2? Maybe for 1969, but I'm more focused on 70-71's.
Thanks in advance!
