Manifold & Risers no longer available

[Jack2048]

I have a '94 5.0 Fi engine with aging risers and manifolds that will eventually / soon need to be replaced. I have looked at many sites, and don't see any available for my engine.
Suggestions on what to do?

simply google "Barr ford marine exhaust manifolds" a dozen places to buy them will come up.

The challenge is finding the Ford risers, which are different part numbers port and starboard...

you started it dry and was ok, you added water and it didnt turn over, you let it sit overnight and it turned over, If this is correct your manifold/riser has a leak in it

Yes. It would run for a few secs on water, then stall. The mating surfaces between riser and manifold were rusty. I filed them down and got new gaskets. Ran the engine for 20 mins to get it up to temp, ran fine.

Yes, it's a Ford 302.

Thanks to all for the suggestions. I'll have a look around. I was just googling the VP part #s which wasn't working.

The elbows for the Ford EFI engines are different, probably has to do with the mounting point for some of the EFI hardware, that is not needed on the carbed engines.

The computer case bolts onto the starboard riser.

Is it possible to make up a different bracket for it so you can use the standard elbows for Volvo exhaust?

I am all for making a bracket. What is considered the "Volvo standard elbow"?
This is the best I can do on short notice, the riser goes into a 90 deg elbow to the exhaust tube.

Look up the same engine but with a carbureted engine.

 

[Horigan]

The Ford EFI risers are different to make room for the larger intake manifold system. The riser/elbows are canted outboard on each side.

So more differences than I thought
What’s a guy to do?
Convert back to a Holley 4bbl?

That's my plan when my EFI system goes TU or I can't get exhaust components. I do have a couple spares of those...
