Oh and I forgot to mention, not sure if this is relavent now, but the original chinook's motor wasn't it's own, it was swapped from a Dolphin of the same year, is it possible it had a different cam? rv cam maybe?, should I try and get that cam back from the yard I sold the chassis to, or should I stay with putting the street cam from LCE? And put it on my current 20r? (1980)
