This is the Leyland version of the twin-bus-engine power plant of the Matilda II infantry tank. From !!!error: Indecipherable SUB-paragraph formatting!!! .

Here’s a pic snaffled from the World of Tanks forum of the radiator setup:

how about a tank engine made up of five Chrysler flathead sixes?

Quiet, you.

Of course, it absolutely makes sense that the Brits bought the majority of these. “lol okay”.

A further note: since it was Britlish Shermans that had these, they would have been serving to a limited extent alongside the Matilda IIs with twin bus engines in North Africa.

Not so much, no. Neither did Tigers, which were designed, every one of them, to be convertible for “wading” with an inflatable sealing ring and other accessories until the factory said “wait, this is stupid” and stopped assuming every one was going to be taken into the water. Or something like that.

What's the story behind this?

For covert tank movements, it was considered necessary to disguise the tanks as trucks in some cases. Such as at the start of Operation Crusader, in which tanks with “sunshields” were moved up to near the Wire (the fence at the Libyan border) more or less in the guise of a supply column until the Wire was penetrated by engineers, then remaining in that guise some way into Libya.

I think it was mostly pointless given that the Germans had minimal air surveillance, but it was a thing they did.

Very funny synchronicity, in that Matildas no longer in use in North Africa were offloaded in large numbers to the Aussies for use elsewhere.

In fairness, Matilda IIs were pretty kickass, despite not being that fast and being terribly armed (40mm). Reasonably reliable for what they were, roomy, and nearly immune to German fire that wasn’t 88s in the early parts of North Africa.

The “except 88s” came up during Operation Battleaxe, in which the Brits attempted to take ground near Sidi Omar with a raft of Matilda IIs after having (unbeknownst) given Rommel enough time to set up 88s just below the horizon.

Rommel apparently kind of liked these - his command captured and reused a few of them.

I like how it’s two completely divorced 4-cyl engines for redundancy. Hence the “ H8".

I thought that might have been the joke you were making. Funny thing - Matra proposed making a two-crank “U8" as an option for the Bagheera.

I’ve been looking at all the info I can find on the Matilda II setup, and I think that while they’re fixed-geared together, the two clutches may incorporate a freewheel on each . The clutch throwout rod appears to operate both. So, one engine can outrun the other at idle or in neutral , the engines can be started independently and clutched in/out smoothly together, and the minute the “lead” engine encounters enough resistance to slow down, it shares the load with the other. Simple. Effective. Smart.

At first, i want to balk at the concept of keeping the engines geared together, but then you point out that it would accomplish load-sharing in a super-efficient manner, and it makes so much sense.

I’d also balk more if these were high-speed engines, but given that they’re chugga chugga truck engines, having them cooperate is easier.

This is an interesting post. It reminds me of a machine I saw in the mid 80s at Fort Polk, Lousiana, where I was stationed. I don’t remember whether it was a compressor or a generator, but it was powered by a Ford V8 that had only one bank with cylinders. So it was a four-banger in a V-8 block.

I have to assume they’d rebalanced the crank and done something for the wider journals and extra oiling holes, but apart from that there’s no inherent reason that can’t be done. V8s as a basis for four-bangers in common production are best known by the case of the Pontiac 194.

A variant block, a special crank, and then most other parts in common with a 389 .

Would that be an automotive application? Seems like a bit of needless weight to carry around.

Pontiac Tempests were legitimately available with a 194 ci four-banger that was heavier than it might have been otherwise and less than ideally balanced. Somewhat disliked for vibration, actually. But - it was a small-engine (?) option for the car. Some needless weight, perhaps, but for the displacement probably not a whole lot worse than a six. Most of the weight of an engine is in the head and cylinder wall s anyway, and it was short one as well as the cylinders and water jacket on that side.

The next generation of Tempest had an OHC six which was a fantastic engine, so I don’t know why other than perversity and being able to make it on the V8 lines they didn’t just offer a version of the Stovebolt before that.

Tangentially related, GM produced in the 60s a four-banger at 153 CID and installed them in Novas and other things. I stand to possibly inherit one of these from a houseboat with low time. The engine was manufactured in 1964. I knew a guy who had one in a ‘68 Nova with a three-on-the-tree. But if I do inherit it, what will I put it in? I am thinking about some sort of very sketchy home built Ariel Atom.

Also, my step dad, way back in the day, had a fiberglass T-bucket roadster — 1932 Model B, IIRC — with one of those Tempest 235s, three Weber side draft carburetors, split exhaust and straight pipes, four-speed trans with a shifter that was straight push/pull and no gates . 104 mph in the quarter mile.

I suspect a 153 is best off pushing something under 2500lb, though obviously “what” remains a question. I suppose it wouldn’t make for a useless swap into a Beetle or Beetle-based vehicle like a Manx.

I’ve seen a miserable four-banger T-bucket or two. Can’t remember what one in particular had, maybe a Lima engine. Usually with a ghastly cheap fiberglass body as well. Never was quite sure if those should be considered worse than a rote, cookie-cutter small block Chevy T-bucket, as the latter is arguably still more tasteful even with a near criminal lack of imagination.

A 153 has the advantage of being a correct sort of look for the first wave of T-bucket roadsters. Not so a Lima. As long as one just uses a pre-70s aesthetic one can get away with a whole lot, but I’ve seen fiberglass 70sish jobs that looked like they were designed by Les Dunham’s eight-year-old little sister. An anachronistic *and* useless engine deepens the insult.

The 153, as I understand it, will bolt up to very many common transmissions. I haven’t looked to see if there are any performance parts.
