225:
...
Minuses: The bore (and bore spacing) is way too small which also leaves us with no room for decent sized valves. It also makes for what is by far the worst bore to stroke ratio of these engines featured here. Also, it only has 4 main bearings while by the mid-70s all of the other I6s of the entire world had 7. Super ironic because the very first Chrysler ever built (in 1924) was the first inline 6 ever to have 7 main bearings. It was a major selling point. And then all these years later the 225 wound up being the last inline six to still be getting by with only 4 main bearings. (Because it has it's roots in the old Dodge/Plymouth 6, not the Chrysler 6.) Sad! Also, it's displacement is just too small to have a fair chance against the other two truck I6s...
I know the slant six is legendary, but I never considered it in the same league as the Ford and Chevy "big" sixes. It was developed to be compact for the Valiant. Its direct competition was the Ford 144-170-200, and later, the Chevy II 194. Stroked to 225, it did ok against the aging Ford 223 and Chevy 235 in taxi cabs and half-ton trucks, until those were completely redesigned for their last generation.
im def biased but i just think the Ford 300 is the best of the 3 absolutely legendary and almost evry guy will tell you what a great motor they are whether it be a dodge or chevy guy

I probably posted in here before but i had an 84 f150 2wd inline 6 4 spe ed(but the one with overdrive) and 2.43 gears. yes it was definetly built for economy and in fact i routinely got 18 and 20 mpg was not too hard, but i still used it as if it was geared for work. burned up a lot of clutches pullin **** i had no business pulling. one time an old heavy double axle travel trailer. couldnt go over 35 but it got the job done.
i was in panama city beach once in the heart of summer. it stareted running hot so i pulled over let it cool down then limped on hwere i had to be 25 miles away. Got out and checked it, no oil no water. nada dipstick was dry. beetween the pan and valve cover gaskets and it needing a ring job it used it all up. filled er up with new anddrove for several months till the oil pump went out. Guy cracked it open to replace and showed me the original crosshatch pattern on the cylinder walls. this was at the 200,00 mile mark. One time when i thought it was on its last leg i put a brick on the gas pedal. A half tank later it ran out of gas. Thats wehn i realized the stories were true and fell in love with 'er. Changed the oil and drover to over 230, 000 before selling to a friend to make room for a 4x4 that never came. He abused the **** out of it bombing down back roads, busting the shocks on jumps, pulling heavy trailers, bouncing off redline. Finally sold it to another guy and as of now it has 250,000 and never been rebuilt. it was run slpa outta oil and water twice, ran hot on a regular basis, and survived my DIY mechanicing. Its a beast. for a ahlf tone work truck that would see heavy abuse and a lot of miles i would find as new as possible well maintained one i could and ride out. for sheer heavy load pulling i may have the ecoboost but for combination of torque, longevity, and forgiveness, i would take the straight 6. Its the motor i would have in my zombie apocalypse truck

No truck at the moment...soon to be a big honkin' gas guzzlin' 4x4!
Great engines all...the 300, 292, 225 inline sixes.
The big truck sixes, although rarely souped up and run in competition have lot's of potential. I've read about one (292 Chevy) in a hot rod body that runs 9's @ 137 mph.
I'm sure the 300 and the 225 sixes would also be competitive.
That particular 292 is actually the rare GMC 302 six, with a set of cut up brodix high port small block chevy heads, turbos, and a bunch of other stuff. I'll see if I can find the link to the build page on it. That guy is considered to be the "big six" (the nickname for the later Chevy sixes) god.

Back in the 40's and early 50's there were a number of GM big six racers..both GMC and Chevy. California Bill wrote an interesting performance manual on souping the Chevy/GMC inline sixes and the old Buick straight 8...all OHV engines.
My favorite six is the Ford 300 but my first car was a 48 Chrysler with 250 CID Spitfire flathead six. The engine was strong and smooth and I never had an issue. I have had most of the domestic sixes over the past 45 years of vehicle ownership. Even though they had a great reputation for longevity I never liked the slant six, the old Chevy stove bolt six, or the early Ford sixes.
I always liked the 194, 230, 250, and 292 Chevy engines and some of the later AMC 258 and EFI 4.0. I had a chance to get a WW2 vintage GMC 270 going and really liked the sound ( straight piped) and was impressed with the power. I have also driven REO 330, Mack 703? (old Army 5T truck) sixes and a couple of IHC sixes which were real power houses.
Memories of old engines are great and the stories in this thread are interesting, however the 300 is the king of all of the American sixes period if you consider the number of vehicles, pumps, and generators it powered and the years it was used. I have owned two and had a work truck with the EFI 300 and they have all been very reliable, had decent power, got good gas mileage, and are easy to repair. My truck now has 236k and I would not hesitate to haul my 4500 lb fifth wheeler to Florida from Mass. Before I had a 300 I was definately a Chevy guy. Besides the great engine the 92-96 F series have to be one of the great trucks of all time.
Its not the fastest horse in the barn but if given the whip can still bury the speedometer.

Not counting the total number of years produced, in the 1960's, the GMC V-6 was the king of stationary six-cylinder engines. They were used by the thousands as irrigation pump engines.

Forgot about those...305 cubic inches...high nickel content in block...used in light and medium duty...very rugged....a real truck engine.
Other engines that were very good, don't know if they have been mentioned....the International gas inline six and their formidable V8 series...which came in 266, 304, 345, 392 cube varieties. Only diff. in size ...was due to bore/stroke.
Tough, durable , torquey engines. Drove farm trucks equipped with these engines.
