VERY useful Jon. 

Will you just LOOK at the weight of a late model Hemi! 

And I thought a Jag V12 was heavy at 684 lbs!

I'm surprised at the weight difference between the Allison 1710 and the Merlin. Or (also in view of the difference in length) would they have omitted the supercharger on the Allison?

When shoehorning model engines into vehicles they were never meant to power I have found the critical dimensions are often the height and width of the rocker boxes at the rear of the engine.

Interesting list Jon.

The 215 cube Buick/Olds is the one which became the Rover V8.
Does "Late Hemi" mean the modern ones or the '64 and on 426ci engines?  I presume the sixties engines as otherwise they are an odd omission.

The Ford Cammer is significantly lighter than the Late Hemi (85lb).  They would definitely have given the blue oval an advantage if they had been allowed to run them at NASCAR events.

The 215 cube Buick/Olds is the one which became the Rover V8.

You can see why it became so popular, it weighed about HALF that of the other V8s.

IIRC the sand cast Rover version was a trifle heavier than the die cast GM versions, but not much.

Did they have an aluminIUM block?

[PR19_Kit]

They certainly did, yes.

The Rover V8, when installed in the MGB, weighed LESS than the old 1.8 litre 'B' engine!

The dimensions on the V-12s appear to be without the propeller reduction gear
assemblies etc. The supercharger assemblies on both types would be removed
for an automotive installation. The centrifugal superchargers aren't really suited
to a vehicle that accelerates and decelerates constantly, they're more suited to
steady speed operation. Which is why centrifugal superchargers dominated in
US oval racing and Roots-type superchargers were the dominant type in Grand
Prix racing.

The V-1710 design is actually quite modular in construction, which is just one of
the reasons that the delay of development of an improved supercharger is puzzling.

Fred, late-Hemi is the 426.

Ah, yes!  This is the engine that made a lovely noise in my brother-in-law's MGB.
