The most complete descriptions of Ford bell housing bolt patterns I've found on the Internet:
If this is a test, then here's what I can remember from memory for the various Ford engines and interchangability.
Y-Block 239/256/272/292/312 - four bolt pattern - unique to this engine family
M-E-L 383/410/430 1958-1960 - five bolt pattern, same as FE, flywheel also interchanges
M-E-L 430/462 1961-1967 - five bolt pattern, different from FE with lowered starter, only a partial match to the FE
FE 332/352/390/406/410/427/428 - 1958-1976 - five bolt pattern
LYB 317/302/332/368 - 1952-1963 - five bolt pattern - unique to this engine family
SBF - 289/302/351W/351C - 1965-1994 - six bolt pattern
385 series BBF - 429/460 - 1968-1997 - six bolt pattern, same flywheel bolt pattern on flywheel flange as the FE
335 series BBF - 351M/400M - 1974-1982 - six bolt pattern, same as 429/460 but flywheel bolt pattern is the same as the SBF.
240/300 Ford Six Cylinder - six bolt pattern, same as six bolt SBF, crankshaft has same bolt pattern as SBF but requires neutral balanced flywheel.
