Hi folks

I purchased a 253 recently to put back in the HQ and i cannot find an engine number anywhere on it. I looked at the two flat areas on the block but nothing. Any clues as to where they hide them? The only number I could find was, 0221 and a clock dial pointing to 6, on the casting on the front of the block.

The other question I have relates to manifold numbers. I have two manifold numbers 2823086 and 9932888. Can anyone tell me the era of these manifolds and what carby would have been on them?

Thanks
