I have a 1989 Bayliner with dual Ford 351ci marine engines (260 HP Gasoline). One motor needs to be replaced(due to internal cylinder rust from possible blown head gasket and extended storage--about 8 years),other engine is good. Local Ford dealer (in Mexico) has a new-in-crate 1992 351ci automotive long block (#92TY6006DC). Is this motor a compatible replacement for the marine engine? (Compression ratio, heads, valve springs,cam lift-duration)? --- if heads are same, should they be pulled and head gaskets replaced with marine gaskets? --- Should cam be exchanged with old motor (it's still good)? Any other pitfalls to be aware of? --- any advice or suggestions will be appreciated.
