This may help, although your engine number doesn't decode. Are you sure it's correct?

As far as I am aware, and I have checked a few sources, it should be a 3-letter code. I can find no combination of C and H together. The closest is CPH which was used for both '71 and '72 454's with manual transmission. Does this accord with your car??
