There are no 428 blocks with an "S" on the rear.
By Dave Shoe - 05/27/2002 6:44:44 PM; IP 63.233.200.86
You may be referring to "part numbers" as listed in some book, as I'm only aware of the "C", "A", and occasional "X" blocks in 428 applications. These characters define the "machining protocol" for the block, not the car line.

The "C" references the reinforced 428 casting and the "A" references the standard 428 casting. Common blocks for a given year apparently received no special markings, so the foundry lineworker didn't have to keep too busy drawing the alphabet in sand.

I'm also aware that sand scratchings such as "C" are reused different years as something else, as a 1961 390 block also got a "C" marking on the rear, and I'm sure it was used other years, too.

The Tbird 428 got the same block casting as the LTD or Mercury. The foundry worker certainly would not know what car the block would eventually be heading for.

JMO,
Shoe.
