So the only difference between the HP and HP2 is the shift it was built on. How do you tell if it was a 440-4 or a 440-6pac engine. Was there a stamp or number on the block. I know the v in the Vin is for six pack engine. Also what does a B stamped on the pad mean. Thanks Bob
Mom & Dad let me buy a brand new 70 Challenger R/T 440 Six-Pack Super Trac Pack when I was 17
