534 Rotating assembly

I want to rebuild a 477 into a 534. Is it the crank, rods and pistons that have to be changed or just crank and rods?

Best I can find, the crank and pistons are different. See post 58 here:

Is this for your bus?

Easy for me to say, but if you are going to repower, go with an oil burner.

The 534 is going to be really hard to find parts for, and if you have a 477 you want to convert, I think you are going to by buying a complete 534 to get the parts.

Not for the Bus, but not not for it either. If I use the bus as a toy before I get around to camperizing maybe, but if I use the Bus for actual camping, it's getting a Diesel for sure and at that point I would probably go Detroit.. 4 or 6-71. Maybe 6v53 if it isn't too wide and hide the turbos under the floor. This engine would be a conversation piece, and only because I haven't laid my hands on a 549 Binder yet.

477 or 534, the conversation will end up on how much gas it uses, and what do you think gas prices will do.

Look for a 534.

The difference between the 477 & 534 is only the pin location in the 534 piston (compression height) which changes stroke length. The rest of the rotating assy is the same.

So I'm just a set of Pistons away. Maybe get some extra dome built in.

You can't put a dome on a piston under a plank head. You could have a flat top with zero deck, and valve reliefs at best.

Can you really have zero deck on these?

Why not? If you're going to build one of these things, I suppose you will do your measuring and figuring with the actual engine. AFAIK that's the only way you will be able to figure out what you want and have it made.

There were turbo units for these when they were put in boats, but I think that was it for performance stuff.

Finding 534 pistons in a full set is difficult at best. Since the plank head is 60 degrees in relation to the 90 degree bore, relieved domed pistons could be made in fit into the 30 degree combustion chamber which is actually contained within the cylinder. Finding someone to design, & do R&D would be very pricey. Better way to go since the engine is very robust and low compression is to turbo charge it, goggle Seamaster 534ti.

Chevy W engines use the same combustion chamber. Even normal 534 pistons should be easy to duplicate. I'm in contact with the guy who parted out some Super Seamsters. He said he has some stuff still. Fingers crossed it's the plenums and manifolds.

I would be interested in Modifying my 534 if I could find the proper plenums & Manifolds.

Is this your engine? Looks good. I'm wondering about the size of the bell. Are they all SAE 2?

Well I suppose it's not zero deck in the traditional sense since the piston is at a different angle than the deck. I guess zero deck would be at the edge where the piston actually meets the block deck.

Yes, thanks my 534 runs like new & sounds great, waiting to install it into my 57 Mercury M600. I believe most SD Engines had Ford supplied Bell/Clutch housings which are unique & not SAE patterns. This info is not supplied in Spicer manuals for casting #'s supplied to Ford.
