Ive read on other posts that this block is an incomplete fe pattern, but will it still mate up? I would not think missing one bolt would be a big deal.

The 58-60 MEL (383-410-430) has the same bell pattern as the FE-

The 61-65 LINC (430) has a modified FE bell pattern. No interchange unless an adapter is used.

-BENDSTENS TRANSMISSION ADAPTORS-

The 66/68 LINC (462) has a dual pattern, the previous HX and the NEW LINC SPECIFIC C6.

What are you wanting to do?

Just toying around it looks like an FE trans will work on a '61 to '65 Mel if the engine block is trimmed to allow starter mount.

Centerline looks on but I haven't measured yet, more to come.
