    Check Alan Colvin's Chevrolet by the Numbers Books. It should be a 275hp 327 with a HCH Suffix code. It should use block casting numbers 3858174 or 3858180. Block casting numbers and date codes are on the belhousing area and the build and vin codes are usually on the front right corner pad.

    327 codes

    the horsepower code should be HC for a 2sp glide 66-68, with ac it would be HF. note that chevy did not use a 600 holley for that engine. 2barrel or quad.
