I know there are some knowledgeable Chevy people on here so I have a question. I got this mostly original 55 Chevy in the shop to work on. I need help to determine what engine is in there. It is not a 265 and feel it is a 283 but the owner and I would like to know exactly what it is. Numbers on the front of the block ,forward of the right head are, FII29D. Anyone help me out.
