For our OLD Chrysler 426 Engines, Where do you get your parts from?
I have a cheat sheet of part# from Advance Auto Parts that I've use worked for everything but the spark plug wires, so far.
Auto places want the car. But I have a boat. They tell me, I can't find it unless it's a car. Well Try a Dodge 440 "426 Engine". I also take off the part and bring it in, and they try to match it.
I still have the point system, not electronic ignition.

Almost all big block Chrysler's share the same parts. Cams, heads, intakes, with the exception of B vs RB motors.
As for the part which broke, I would remove it and have one made. I don't know what its exact shape and function is, but I don't think it would be too hard to make.
I would imagine that some of the marine exhaust parts like that one, would be very hard to find.
Then again, it might be here:

The fuel pump may be here: w**.hurrikain.com/Chrysler-fuelpumps.htm
The engine parts, on the other hand, are readily available from the aftermarket.
Since this is my first post, you will have to add the http and www to the links above.
I would also replace the old ignition system with the electronic. I have probably bought at least 20 of the conversion kits for cars from Mopar Performance. It provides a hotter spark, the plugs last longer, and better performance. It is about the first thing that the automotive hot rodders do to the sixties muscle cars. You may also want to upgrade your ignition coil.
A suggestion, after you convert to electronic, keep the original distributer and other parts in the box the conversion kit came in and keep those on the boat. Although it is rare, I have had a couple of the relucters fail. On land, it wasn't that hard to get towed home. At sea, that may be different story!
I didn't see an introductions page, or I would have introduced myself there. I am a friend of Paul45C.
