My 53 Ford Flathead had a wrap around pipe for duals that was available aftermarket. later model manifolds with rear outlets would make a much neater setup.

In a Ford, especially 54's, it was common practice to run a pipe down and back from the drivers side manifold (opening in the front) because either the neutral safety switch was in the way or the Z bar was in the way if using a later rear opening exhaust  manifold.  Sounds like what you are describing, but only on the passenger side.  Not familiar with the Lincoln exhaust system .

368 is the same block as a 317 so it should bolt right up

I'll check with my mechanic and see if he knows. He seems to know y blocks.

Actually I should have several extra 368 exhaust manifolds.  They would be an easy solution but I do not know if they would fit a 317.  

The above discussed method for dual exhaust was a somewhat common practice on 64 and earlier trucks due to the location of the steering box. A left side car exhaust manifold would not work in this instance.

I don’t remember y-block Fords ever doing the wrap down pipe since duals came out on all 55-up Fairlanes. The left sides were readily available in wrecking yards or dealer. It seems the newer Lincoln would be the way to go if you can find one or both.

Gabriel's horn is a term I've heard for the turned down exhaust pipe on the driver's side manifold where the crossover was. Sorry for the confusion as I thought it was a phrase commonly used in the Y-block world for this method of adding another  exhaust pipe on the left side.   As for being a biblical term, well, I don't know about that.   My point was, a pair of 57 or maybe 56 Lincoln car manifolds may solve the problem of adding dual exhaust IF there are no chassis  obstructions,  like the steering box etc..  That would make the task much easier and look very  clean. I know a usable pair of Lincoln manifolds will be rare but one never will know until some searching is done.

I don’t have clue what’s going to work on the Lincoln. But those front crossovers can be reused by routing the drivers side any way you can. Down and back. Down, across, and back parallel to the pass side. I suppose you could even leave the crossover up high, turn it down in front off the pass manifold, then run it back. You’ll need a block off plate on the pass side where you disconnect the crossover. All depends on what you’ve got to miss and where there’s room to get the exhaust pipe out.

It’ll clean up the engine a little, but I doubt there’s much performance gain with a full exhaust system.

I think “Gabriel’s horn” is a biblical reference I won’t go in to.

I don't know what the Gabriel's horn method is. I heard I could eliminate the crossover pipe and curve the pipe down in the front of the engine bay then back. I know there's a lot of room on the passenger side so that's why I was thinking of crossing the pipe between the passenger side manifold and the inner fender then running it back from there. I'll see if I have a picture of the engine from before I pulled it.
