Just for Clarification:

That number along with the "partial VIN" is referred to as the "deck stamp".


The casting number for the black is at the rear of the block where it meets the bell housing

Welcome Ian, to Team Chevelle.....

The last 3 letters (EDH) of the suffix code denotes to: 1966 396 with 4 bbl carb, 325 hp, manual transmission.

When I thinks, I falls asleep.

Re: Casting # on 66 SS

I think the H stands for the carb being a Holley as some 325 HP's were quadrojets and some were Holley Is that correct or did I remember it wrong.Almost forgot Welcome to the Team

Correct. Although every 66 Impala 396/325 I have ever seen had the R code for a quad, and every 66 Chevelle 396/325 I have ever seen had the H code for a Holley. Not sure if they ever actually built either of them the other way around, although both the quad and the Holley are shown as possibilities in both the Impala and Chevelle Assembly Instruction Manuals.
