Casting # is stamped on the driver side of the block!!!
Reply:If you're asking what the original engine of your car was, I believe it is the 5th character of the VIN - at least in '66 it was that way, but for all I know '66 could have been a new way of doing things for Mopars, much like '69 was for its codes on the data plate under the hood.





If it was a '66, I'd know "H" was the Hemi ("J" was Hemi in '67, despite what some manuals say) but the Hemis in '65 were race-only, and I am not sure if they were available on the Belvedere II. But the top street engine in '65 was the 426-S, rated at 365 hp. Next step down was the 383-4, then probably the 361-2, 318-2 (the "old" 318), 273-2, and Slant Six.

Reply:B/RB Block Identification Some Mopar Information





For Engines made begining in 1965, again the first character indicates the year [ A B C D E F G H J ] for [ 1965 .. 1973 ] (in set order). The full CID displacment will follow. If a dash and three numbers follow, this indicates the date it was stamped (not necessarily cast). Some of these engines will be stamped with an HP indicating that it was destined for a high performance application. Likewise, a L or LC would indicate a low compression engine. This isn't an either/or relationship. A block might not have either an HP or an LC. And not all block that wound up in high performance applications always got a block stamped HP.
