Boring comparison

Left is a Chevy 350




Left is a Chevy 350 jug, +0.030" over. On the right, a V-12 Ferrari one, standard bore.

The Ferrari as I recall was initially a 3L overall displacement, not that big when divided by 12 individual cylinders

Then there's the Beast of Turin:

How about a 1.5 litre V16 BRM

 

[mezy]

now i bet that thing will rev.

 

[JHaydon]

1.5L / V16 = 93.75cc per cylinder -- wow
600bhp / 1.5L = 400bhp per liter -- YIKES
600bhp / V16 = 37.5bhp per cylinder -- comparable to the entire output of the 1200cc engine in a 60s VW Beetle!

I was lucky enough to be competing at Shelsley walsh when they were celebrating the BRM marque
So could get up close and personal. And to hear the ridiculously glorious sound
One V16 is a factory recreation.
And how about this rear brake system on another model !!

it’s reported to be 12000rpm and equates to about 185mph subject to gearing. In period. But notoriously unreliable.
Perhaps the recreation has had the bugs removed ?
But what a car for the period.

From Wikipedia on the BRM P48's transmission mounted brake..."the unlovingly nicknamed "bacon slicer" rear brake."

I noticed that monster trucks have one big disc located on each drive shaft.
None I think on the axles.

A bit more on the V16 (showed up on my Facebook feed)

The idea of a 1.5L V16 seems hilarious by modern racing standards, especially to us in the land of BangShift where 900-cube V8s are prowling drag strips. That being said, in the world of Formula One racing back in the early 1950s engine designers had a choice. They could design a 4.5L naturally aspirated engine or a 1.5L blower motor.
BRM (British Racing Motors) decided to go the 1.5L route with their V16. It sported a comical 1.95-inch bore and 1.9-inch stroke. It was capable of 12,000 rpm and when equipped with a Rolls-Royce two stage centrifugal blower the engine made 600hp. Reportedly that Rolls blower was forcing 82 pounds of boost through the engine!
Interestingly, the engine featured two valves per cylinder. We’re guessing the tiny bore may have been a factor in that. These valves make Buick Nailhead valves look massive! How about 1.25in on the intake and 1.09in on the exhaust?
It’s no wonder why Formula One cars were revered so much back in this era. An engine like this in a custom racing chassis was the space shuttle of the day.

But strangely, that photo isn't of the BRM 1.5L V16...It's a photo of BRM's 3.0L H16.

BRM's 1.5L V16

 

[Bayless]

Both are really impressive.

Can't recall who said it... Someone once pointed out to me that "today" (60s-80s), the best & brightest engineers design spacecraft, but in the 1930s-50s the same cream-of-the-crop engineers were designing automobiles.

Seems to me "today" the best are designing "bitcoins" and other fictional nothings

Those aren't the best.

I'd argue the Webb telescope and landing on a comet hurling through space. Helicopters on Mars anyone?

Agreed.
