None.
There is
no way to determine FE engine sizes by numbers cast on engine blocks or by looking at them, as all pretty much look the same.
Thru circa 1971, 352 is cast onto the block, but this is a foundry mark only, as all FE's were cast as 352's. So, it could be a 352, or who knows.
You will need a 390 used
after 1964, as 1961/64's were only installed in cars, have a different engine block bolt pattern for the front rubber insulators.
1958/64 FE engines have rounded valve covers without holes in them for smog valve/oil cap. There's an oil fill tube on the right (passenger) side of the engine.
1965/76 FE engines have pent roof shaped valve covers with holes in them for oil cap/smog valve.
The list of vehicles that came with 390's is mind boggling, too extensive to list. Plus, other FE engines were also available in these same vehicles.
