I have a 1978 C65, single axle dump truck, and I wonder if there is any way to identify whether the
engine is a 366 or a 427. This truck is one of the years where they were changing the format of the codes,
and the engine type is not listed on the tag.
I don't know if this information is helpful, but the engine is a light blue colour, and is coupled to a 5 spd transmission
and a two speed rear axle.
