Went to a cruise in at our local DQ last night. Was standing by the Sub with the hood open and this guy comes walking up and he says, " I see you have Power Pack heads on your 283, those are semi-rare"and are 10/1 compression". Now I have not heard of power pack heads. My engine was built up out of parts I scrounged from various sources including a couple of junkyards that I visit frequently just for entertainment. Any body know what this guy is talking about? With all the small block historians on the Stovebolt I figure maybe someone can tell me what I have here. Thanks in advance.
