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?
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.
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

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. Image Unavailable, Please Login
