That's for a small port 3100, different configuration.

Obviously, the lower intake and heads would need to be used from the 3.1 and/or 3.4

And then the next question would be, does the distributor fit

You would need LIM and heads from a 3100 or 3400. But since the UIM appears to be from a small-port 3100, the LIM from a small-port 3100 would probably be more appropriate.

That intake with a large plenum and long runners would not be the best design for performance.

The air fuel mixture coming from the carb needs to be kept turbulent and flowing. Having a big open space like that does not help metering and atomization.

I would go with the Edelbrock which does work well, but if you can find one, the Offenhauser is better. It is race proven and harder to find but worth it.

Didn't someone on the forum do this mod on a track car? I seem to remember it being discussed before.
----- Think I found the one I remembered -- Titled - OH! NO! I have a 49 mm hole in my plenum

So after all the trouble of getting 3.1 heads and lower intake swapped out so that this plenum would bolt on

...You would need to cut a hole in your hood to clear the carburetor

Depends on the air cleaner.

This is the back end of two 3.1 upper manifolds cut off and welded together. Note that there is no stock throttle body mount anywhere on the manifold other than the carb mount. In the Craigslist pictures there is a weld across the underside of the piece.

I think for aluminum it is called zyglow or something like that. It is a dye type process that uses ultraviolet light to see cracks. I may be wrong on this, but I have been wrong before.
