Radial engines favored for powering the tanks & AFVs, 1935-45 (2 Viewers)

It doesn't change - radials aren't the right choice for AFVs.

Was that also the conclusion of the folks that drove and fought in the radial-powered tanks?

Hard to say, for the Soviets it was radials vs diesels.
A lot of crewmen blamed the fuel for fires and not the ammunition so perceptions are screwed up.
British in NA were comparing good radials to really, really crappy Liberty V-12 installations. If fact the radials may have been only mediocre but compared to the Crusader tanks the Radials just looked good

It is worth noting that the US was still using radial engine vehicles in 1953 if not later but ALL of those were left over WW II production. Only the M36B2 shows up with the twin diesel engines.

The only new build M36 were the 187 M36B1 built Oct-Dec 1944 on M4A3 hulls, to make up the required contract numbers.

Fisher built 300 turretless M10A1 hulls Dec 1943-Jan 1944 which were used to produce the first M36 with the addition of a new turret with the 90mm gun. Attention then turned to reconditioning M10A1 TD retained with training units in the USA and replacing their turrets. And finally as M10A1s began to run out attention turned in May 1945 to reconditioning diesel engined M10s as the M36B2.

So no opportunity to redo the the M36 drivetrain without spending a lot of money.

You missed the point, I think.

The M10 should have just been an interim, for training and limited combat- Substitute Standard, in US Army speak.
Buick had the 76mm armed M18 in production at Flint in July, 1943 for initial Contract for 8986 units

However, only 2513 were built, production ending in October of 1944 from two far smaller production contracts.

This was mostly from McNair and AGF who (foolishly) wanted more towed AT guns than TDs, with the number of planned TD Battalions halved in number in late 1943

With the M18 in full production, Fisher could have retooled to make a proper low hull using M4 components.

The M18 could use the lower torque Radial successfully from the Torqmatic transmission

Let's throw out the diesel as its tough to compare very different fuels...

Had the V2 been set for Gasoline, it would have been a 700HP class engine. At the end of the day, Torque is all about the bore and stroke of its cylinders, and at what RPM they are operating at- not what hydrocarbon is in the combustion chamber

'No replacement for Displacement' is a valid saying.
It's the cheapest way to get torque.

People talk about HP, but they all drive by Torque.

And a tea kettle, right?

They weren't Barbarians, though had to live rough till the first 'civilized' Tank had one from the factory- the Centurion.

I would delete the Hall Scott engine from the list.
It was interesting and the right power but anybody who put it in a tank needed to be taken away to very quiet place with men in white coats to rest for a number of weeks/months.
It was a very good boat engine but a 3650lb engine should not be going in a tank.
Edit, Torque peak was down around 1400-1500rpm.
