Hmm.
I listed it on ebay for a 6m6 and the guy says it doesn't fit.
sigh.

measure the distance, on center, between the two bottom bolt holes (the ones under the "2" and "0") in the pic.

the 6m6's are further apart from each other than the 61x's.

if you can provide the measurement, i can tell you what its for.

He probably has 61x cases and not 6M6.

How much further apart are they?

If I zoom in on the picture my stock 6m6 manifold here lines up perfect on my computer screen.

The two outer-most intake manifold mounting holes on the 6M6 Cases stick out (away from the rest of the motor) quite a bit further than they do on the 61X cases.
The manifold in the picture is definantly for the 6M6 cases.

Eric.
