6 cylinder Maser engine!- dreadful old things, longer stroke than an XK. Wouldn't do more than 5K if the flywheel fell off; waste of 3 good weber carbs. If you want a real engine, the Busso Alfa V6. The Lampredi IL6 in the Fiat 2300 is pretty good too. Much as I hate to admit it, the straight 6 BMW engines are stunning, even those derived from the 328 - did I mention Bristol?

 

Wake up to yourself Arthur!

 

OK, I'll give you that one - but the production engines - 3500, Mistral etc were long stroke horrors, there were much nicer(6 cyl) engines around in period; XK 3.4, Aston, Lancia, Fiat, Bristol, Merc.

Of course, not talking about outright power, but refinement, there is nothing to beat the RR/B60 or the Rover IOE 6 cylinder engines. The 7 bearing crank Rover engines were amazingly smooth - I had a few P4s, and no, they weren't a Jag, but they did what they were supposed to do very well..

I forgot to add, The Armstrong Siddley Sapphire engine was pretty good too, but not intended as a performance engine.

 

Motec!

the 2300S engine was the first motor Lampredi touched when he moved from Ferrari, the head is so wide I thought it was DOHC at first

Mine pulled 7500 when it was in good tune, 6700 all day when sick as a dog

 

nice engine bay, who's car ??

 

RP's i'm told.

 

Bugatti's 16 valve engine

LT5.


Designed by GM and Lotus in the 80s.

Introduced in 1990. 5.7 Litre, 375hp (405 from 93).

And did all of this:

Although the ZR-1 was extremely quick (0-60 mph in 4.6 seconds, and onto 180+ mph), the huge performance of the LT5 engine was matched by its robustness. As evidence of this, a stock ZR-1 set a number of international and world records at a test track in Fort Stockton, Texas on March 1, 1990, verified by the FIA (Fédération Internationale de l'Automobile), including seven new international records:

* 100 miles (160 km) at 175.600 mph (282.601 km/h)
* 500 miles (800 km) at 175.503 mph (282.445 km/h)
* 1,000 miles (1,600 km) at 174.428 mph (280.715 km/h)
* 5,000 km (3,100 mi) at 175.710 mph (282.778 km/h)
* 5,000 miles (8,000 km) at 173.791 mph (279.690 km/h)
* 12 Hours Endurance at 175.523 mph (282.477 km/h)
* 24 Hours Endurance at 175.885 mph (283.059 km/h) for 4,221.256 miles (6,793.453 km) (World Record)




This was at the time of the 348 with it's 300hp and 5.4 seconds 0-100kmh.

Yes, it's an American car, but without cars like this, the car industry would be very different.
