AMC AMX Javelin Rambler scrambler & others 390 engine block core. 1969. Someone had this face down in the dirt. So the front of the block would need to be epoxied and surfaced back down. It could be fixed other ways but I think that would be the least expensive. Mags good, and The block is standard now, and I think 0.10 to 0.20 would clean it up.
