GM's 4200 Vortech (Atlas family). Basically a long-stroke Ecotec available in 4/5/6 versions. I'm partial to the 6! I just wish the General would put a 6-spd version into something fun. It's been on Ward's Best Engines since it's inception.
BMW: Have you ever driven an M3? Wow.
Out of loyalty, I owuld mention the Pontiac OHC-6 (66-69), but sadly, I wouldn't rate it in the top 10. Waaaaaay ahead of it's time with belt drive, finger-followers, 'and Johnson' lash-adjusters. Right engine, wrong time. In the 70's, it would have been killer if America wouldn't have been willing to accept something other than a heavy V8 sedan!

Im leaving brand loyality out of it....but im still going to say the 300 Straight 6.
Out of the gas straight 6's, they by FAR have the most torque, the best reliabilty, and the most charcter.
Close is the old 292 Chevy 6, but they still wont outwork a 300.
The 4.2L GM inlines arnt bad engines, but they arnt the workhorses the old engines were.
The inline 5's are garbage.....they shoulda kept the old standyby (4.3L).
later,
Dustin

2JZs are the best to me. able to hold around 900hp on the stop bottom-end (with ARP hardware)
1JZs are next on my list. able to hold around 750hp
How about an Inline 6 Formula One Engine?
Maserati TIPO 250F
Years of production: 1954-1958
Straight 6-cyl 2493.8 cc engine
DOHC with two valves per cylinder
Bore 84mm and stroke 75mm
Compression ratio 12.0:1
Power output 240/270bhp @ 7200/8000 rpm
Induction system by three Weber 42 DCO3-45 DC03 carburettors (in 1953 also direct fuel injection).
This engine powered the 250F single-seater with which Juan Manuel Fangio won the 1957 F1 World Championship. The 250F single-seater had a very long and successful race career taking part in all F1 World Championship races from 1954 to 1960, when a change in the regulations for Formula 1 restricted the engine size to 1.5-litres.

4.2 not a workhorse? 291hp and 300+ ftlbs of torque (and underated at that) not enough to compete w/ the older engines?
5 cylinder garbage? What is this based on?
It's fine if you don't care for them, but lets see some if you can add some meat & potatoes to your statement there...

:Toyota 7mgte isn't too shabby. It can be had cheap, with tranny attached, and make around 400hp in nearly stock form with some easy mods and will fit a mustang or falcon fairly easily.

I have several candidates for the best inline 6.
The Cummins 12V first gen Dodge turbo diesels. I had one with 300,000 miles on it, and after sitting outside for 4 years uncranked in a 1 ton 4WD Dodge pickup, it started in half a revolution....... in the winter. It's got a Holset turbo, mechanical direct port fuel injection, a maximum operational speed of 2,800 RPM, has 460 ft/lbs of torque, and still has 40% less moving parts than a conventional V8 engine. It's 5.9L (360 cubes), and holds one full case of oil in the crankcase. Plus it sounds insane, and is easily capable of over 600 ft/lbs of torque with less than $1,000 worth of bolt-ons. This engine attached to a Getrag 5 speed manual transmission will last you 400,000 miles before Cummins recommends a rebuild. After that, the engine will be set for another 400,000 miles. We had a guy on my old Cummins Turbo Diesel forum with 1.2 million miles on a 1 ton Dodge truck powered by a Cummins Turbo Diesel and a Getrag 5 speed. most guys had between 275,000 and 650,000 miles on their Cummins. Mine had 300,000.
The second candidate is the Nissan RB25DE. It's 2.5L, features aluminum block and head design, and has dual overhead cams. It can rev to ungodly limits, and is crazy powerful. With one or more turbos, you can get easily over 700 HP from a streetable engine. Props to Nissan for showing the kind of impressive numbers an inline 6 is capable of.

My favs have always been the Jag 4.2L, The BMW M3, and the Nissan 280Z
A kid I was good friends with in High School was English and his dad was here in Indianapolis working for Lily as a Chemist. Dad had a V12 Jag and for his son he bought a XKE with 4.2L I6 and it was the father/son project.
I have always loved the Bimmer I6's. Always seemed like the underdog.
A good friend had for many years a 280Z turbo that was pretty darn quick. The engine was still running great when he got rid of the car cause the body was shot.

My wife's family had an '88 Toyota Cressida with the 3.0L Supra engine (not sure of the number), and a '92. Those cars were absolute animals, basically a BMW for half the cost, and dead reliable.
Sneaky fast, the kind of car you'd look down and see that you were "cruising the ton". Wish we still had them - I know that the '92 is still running with 250+k on it.

Sure were realiable beast. My neigbour has two, an 88 2.0 liter Jap import, and an 88 New Zeland market 3.0. Each has over 185 000 miles on the clock.

I would vote 2jz-gte but im somewhat biased. I've been lucky enough to drive a 1000hp drag car with a stock 2jz bottom end, and have had several 2jz-ge engines come in flooded from high water, only to leave after i pull the plugs and crank it over a few times. as far as reliability i rarely see anything but the occasional a/f sensor go bad.
