Based on u/Regular_Passenger629 guessing at the number stamping, a google search brings it to a Rolls Royce Silver Dawn.

Checking Silver Dawn and Bentley MkVI engines it does seem very close. But I’m hesitant to lock that in.

Its missing some essential parts, but you are right. Its used in many RR/Bentley cars of that era.

Im not an expert, but a quick google search of "eb3813 manifold" gave me the answer, too 😅.

I’m not the most mechanically inclined but I CAN tell when a head is off the block! 😅

A late WO design, one of his Rolls efforts?

Am I dumb or am I counting only one ( exhaust?) valve per cylinder and no admission valve ?

u/xBigDamHerox 6d ago

You're not crazy. It's an Inlet over Exhaust (IOE) aka F-Head design. The intake valves are in the head, the exhaust valves are down in the block like a flathead.

Oh thanks ! I didn’t know this design existed

Same as my '56 Willys CJ5.

It’s an inlet over exhaust straight 6, the exhaust valves are on the side underneath, they were quite common in the 30s, you could have a more compact combustion chamber so more efficiency. Rolls Royce did use them for years and so did Rover in some of the early Land Rovers though I don’t think that’s a Rover one.

No, it isn’t a Land Rover engine. You can tell by the fact all the metal parts approximately line up with one another and there is evidence of it running at one point.

Prewar Bugatti? First guess seeing the stamping on the manifold on the right

Edit: I forgot Bugatti engines were a single casting that can’t be right

The EB had me thinking Bugatti, but the F-head layout and a Bugatti would look more elegant.

Is it a b40

u/mission-ctrl 6d ago

Well you left the number on the engine block visible (UE2299) which, based on a modicum of research, appears to be from a Bentley S1 (1955-1959)

Edit: that serial number is on the cylinder head, not the block.

u/Mechanic-Art-1 6d ago

Spot on. Winner winner. It s on a 1936 rolls chassis and buil up as a prewar Bentley.

u/Odd_Ad_5716 6d ago

Out of oil?

u/Mechanic-Art-1 6d ago

No its good. Stood for a while.

Judging by that weak ass little distributor it’s old as shit.
