Would that be for a C3 427ci. car from 68-69 as per Homologation 583? If so I think there are countless reference of blocks available for these cars and no we do not work with formal listings. Here there are possibilities of 427 ZL1 Alloy or Iron blocks I presume?
Basically there are countless numbers as there were truck, standard or even marine applications in some cases. 3782870 for an iron 4-bolt tall deck and 4.250 bored block I believe produced from 1968 to 1976 and 3946052 for a 427, 4.250 ZL-1 MkIV 1969 period block.
There are online database as well as books which are just about GM casting numbers and which most builders and/or specialist often refer to when submitting applications, or simply providing a copy of the record.
