375 HP in 1965

Yes, I stand corrected.
I think the 365 was 2x4bbl? Single 4bbl? Carter AFB? Holly? Quad?
My brain cell fails me.
But I'm still looking for a correct answer to the 'what came after the 6cyl in the 'vette' question.
Too much is never enough
Don't believe there was a 365. My '62 Fuelie was 360 HP and the two quad version was 340.

I believe the L76 motor was 365hp.
But, Like I said, I'm down to a SINGLE brain cell (active) and may yet be wrong:

There WAS a 365 HP Corvette Motor - see link for the whole history

Bingo:
The Corvette L-76 was a 327.
I think it was 2x4bbl and probably had a nice, lumpy idle.

was primarily used in trucks

According to wiki the 6 pot was simply deleted in '56 and the smallest engine option was then the 265 (4.3L) V8 with between 210 and 240hp.
Engine size increased to 283 cu in in '57.
yes.
In modern lingo, it was a 4.3
Not the smallest V-8 ever but certainly on the small side.
Today? Their are supercars with smaller than 4.3
Too much is never enough
No but this may be the smallest V16 ever:

It's a supercharged 1.5L (91 cu in) F1 race motor designed by BRM in 1947.
By 1950 it produced 600hp @ 12000rpm although not very reliably!
I just realized that the BRM was NOT a 'Vee' engine but rather an 'H' configuration.
This was accompllished by basically stacking 2x FLAT EIGHTS on top of one another and GEARING them together to a common output shaft.
Needless to say, it was mechanically complex and just the plumbing alone would give you a headache.
Too much is never enough
No, different motors but I mistakenly linked to a picture of the H16 when I meant the earlier V16.
The H16 was indeed made from two flat8s but it totalled 3000cc and was normally aspirated while the V16 displaced 1500cc and used a centrifugal supercharger made by Rolls Royce.
Some years ago I've seen it at Goodwood. The motor looked almost toy like.
Didn't sound like one though...
Finally found a photo of the V-16 and it LOOKS like almost the nightmare the H-16 was!
And the callout I read says it was a nearly Square design so it limited valve size.
I'd love to see a short stroke RETHINK of this engine. It must have been incredibly robust to sustain the boost pressures the article quotes.
Too much is never enough
It was quite reliable eventually but unfortunately by then the F1 rules had changed and it was obsolete.
Interestingly, that's a H16 pictured.
You're right.
Here's the actual V16... I hope.
The smallest production V-8 I know of might be the BUICK engine which was eventually sold to Rover who continued production and development. At 3.5liters? pretty darn small.
The Buick original was Aluminum Block.
Too much is never enough
I know they made various very small displacement racing engines in the 1960s. Not sure about the V8. The V12 was 1.5 liters.

500cc 130HP at 23,000 RPM remember?

You guys keep going to racing autos.
yes, some really wacky stuff has been made for racing. The honda 'oval' cylinder is one terrific idea but I think you'd need a pair of 'em in an opposed or 'vee' configuration for balance.
But for production autos? That Buick / Rover V-8 is the smallest I know of right off hand.
Too much is never enough
Daimler 250.With a 2.5L V8 which the designer based on a Cadillac V8 which he shrank down until it would fit Triumph motorbike heads.
BMW offered a all alloy 2.6L V8 in their 502 from 1954.

What a dog of an engine!
The 4 cyl Dolemite Sprint engine was already a nightmare. What could go wrong by mating two together into a V8?
Cheers,
