I'm trying to decide whether to keep and build or sell this block. I need to know if it is valuable for restorations. If I sell it I want to get a fair price. Foundry & date stamping: GM 340P 35060091 (Mound Road Detroit plant, March 4 1971, 91st block that day. Block has never been honed, never had a piston in it (bore 4.0325").

Trying to insert photos. Do they show-up?
