So I was looking for a set of camel bump heads that are meant for the 327 in the truck, and soon enough I found this engine...motor is a 4 bolt main 1970 350
And it had camel bump heads on it...
Part number #3973370...no listing in the Chevy part numbers anywhere...read somewhere maybe marine 64cc heads from yacht or GM performance over the counter heads?
Was some porting done...
