I had a 65 F100 custom cab with the 240 I6. Reliable as hell but pretty anemic. Wish it had the 300.

Had a 1977 Mercury Monarch (Grenada cousin) straight six and four speed. The water pump died and I drove it home in the middle of winter, empty of water. Twice I pulled over because it got so hot it died. Let it cool, started right up and drove again until home. Changed the water pump and it never even burned oil after that. Bulletproof.

WAY overbuilt for the power it produced. They last forever since they only make 87 HP.
I owned one in the 90s. |

Had a 83 full size bronco with the 300 and 4speed.
0W30,huge battery and a hand choke she started in the coldest weather. Just did not put out much heat. Body fell apart and I did not want to spend the money on it. |

My senior year HS auto shop project was a rebuild of a 240 I-6 which was the smaller version of the 300.
My Dad's 66 F-100 with a 3 on the tree. Lots of good memories. Seven main bearings and a gear driven camshaft (no chain) made these things pretty built-proof. Currently own a 63 Comet with a 65 200 6 (different engine than the 240/300) but for what it is I got no complaints. Also a 3 on the tree, or as I call it a modern day anti-theft system.... LOL |

My 1st pickup was a 77 F250 high boy 4x4, 300 six with 4 speed manual.
Bought it new and it was dead reliable. Not fast but, it had a lot of torque. |
|
6 bangers are cool. Back in HS a buddy drove a Valiant with a slant-six and a Hyper-pak intake. He added headers and a bigger carb, made for a peppy little car.

Have had several. Damn things are Bombproof.
I put a new dash in one, at 300,000 miles, and sold it a year later for more than I paid for it, as Mileage unknown. They make good power down low, to mid range, where it counts. Add an Old pre-smog Offy intake/header and they will embarrass the old V-8's and some of the newer stuff that will never last. The biggest weakness is the damn things frost up quick in a wet snow, and the stupid engineers only answer was a flimsy heat riser and vapor locking. That is an easy fix with the Offy intake and a proper carb tune or EFI. Get ready to go down the Rabbit hole, and meeting all kinds of grumpy old Farmers and sicko Motorheads. The 300-I6 is one of those things that easily become an obsession. Pro-tip... They outlasted their axles, and frames, and there are thousands of them in various states of decay in Rust belt wind rows. The Western state trucks sucked grit, until compression was gone. Oil bath filters were horrible. Save your time and $$$ and scrounge upper midwest wind rows first. Usually new valve seats, decking and line boring is all that is needed. Half the time, the Mains are just starting to scuff at 200K miles. I sold off my stash, but there are 3-4 waiting to be shown some love, within a couple miles of here. Hell, there's a Turbo hot rodded 70' sitting in the corner of a hangar you could probably snag for cheap, just up the road.....with a roached 8.8 Build and resto pics!!!! |

Good reliable but low power. Don't believe the 6 straight myth of torque monster. It is untrue. Enjoy your project.

I had a van with one.
The vacuum line to the transmission modulator came loose so I decided to replace the old line. When I got to the carb and pressed the line on the whole carburetor moved. I could rock it back and forth at least a 1/4". She still ran just fine. Tightened the bolts up and went on my way. |

My dad still has 1984 F150 with the 300. My daughter learned to drive a stick last summer with it and she was 12. I bet the truck has 275,000 miles on it.

I've owned a couple stock 300s over the years, and loved them. Buddy of mine had his rebuilt a few years ago, but swapped the 300 head for a 240, shaved it, then added an Offenhauser 4V intake, headers, 390cfm Holley 4bbl, and a Comp 268 cam. Pulls like an absolute bastard with the 4.11 rear end.

Quoted: My 1976 F100 has a 300 I6 with a three on the tree. The engine and drivetrain are so reliable that I will never sell the truck. View Quote My dad bought the exact same truck in '76: F100 I-6 300 w/three on the tree. In '80 he swapped the tranny to a 4spd on the floor and added more leaf springs in the rear and ran it in his construction business until '92, when he gave the truck to an employee. When he gave it away it had 350,000 very hard miles. |

I did tree work in college, thirty years ago, and the guy I worked for had a chipper with a 300 six. It would literally chew thru anything you tossed into it.......
And it scared the shit out of me every fucking day at work. No safeties, no guards, just that unstoppable engine. |

My buddy has a 74 f250 with the 300, vs mine 72 f250 with the 360. They drive about the same after he did exhaust, put a nice head on it, and got it tuned to perfection.
But it sounds like a ricer tractor, fuck nah. |

Quoted: I don’t think the slant 6 needed oil. Ever take the valve cover off one? Dry as could be, I have no idea how they didn’t self destruct. Unbelievably reliable. View Quote View All Quotes View All Quotes Quoted: Quoted: Quoted: Chrysler made a slant 6 that was even more indestructible I watched a buddy change the oil in his old slant six Dart. He drove it up on ramps, drained the oil and swapped the filter. Then he fired it up and backed off the ramps to add the oil. Said it was up too high to add the oil when it was on the ramps so he always did that. It had so many miles on it the odo didn't work anymore so he had done that a bunch of times. Still ran and sounded fine lol. I don’t think the slant 6 needed oil. Ever take the valve cover off one? Dry as could be, I have no idea how they didn’t self destruct. Unbelievably reliable. Had an old Chrysler mechanic tell me, don’t change the oil after 60k miles just add more when low. The dealership had an early 60’s valiant as a shop car. Odometer had rolled over x2 and was still running strong. Thing had a push button trans shifter. |

Had an '82 F100 with the 300, 3 speed manual column shift. Awesome engine.

Had four of them over the years…very sound engine, never had any issues with any of them. Mate them up with a five speed manual tranny and change oil regularly and gtg….

I had a 1987 F250 r/c 4x4 with a I-6 and a 4sp manual. The thing was a monster. It wouldn't go over 75 mph, but it would tow or pull anything you threw at it. I miss that truck.

I have owned three of them.
Never turned a bolt on any of them except oil changes. The last one was fuel injected. Made a ton of difference in the smoothness. V-8s are sexier, but the old 300 CID I-6 is like others have said bulletproof. |

About three weeks ago, I got this running in a couple hours taking my time after it had sat for maybe 10 years.

The 240/300 are bullet proof. Had a 240 in my '74 short bed and a 300 in my '80 Bronco.
Regular maintenance and changed belts, water and fuel pumps, alternator and starter. 200k + miles. |

With care and maintenance, the ones still out there today could likely keep running longer than anything else on the road today.

My last dump run with my '79 F-100 which has an inline .300 ci six was interesting. Somehow the petcock on the radiator opened up and I dumped all the coolant. I got it home, checked the oil and no water in it.
It starts fine and runs fine. I know that normal engines with aluminum block and head would have twisted the head and blown the gasket, but this old cast iron workhorse made it through with no ill affects. Three on the tree and manual steering, what's not to love? |

Had a 66 F100 with a 240 in it. Did a tune up on it once and I guess I forgot to tighten down the distributer clamp. Driving down the highway a few hours later at night, we suddenly notice an orange glow from the cracks of the hood. Pull over and lift the hood, the exhaust manifold and the block around it was glowing bright orange like a light bulb. The distributor had moved and it was running super lean. Sat on the side of the highway for 20 minutes while it cooled down enough to get near it. Turned the distributor where it needed to be, tightened down the clamp, started it up and drove off like nothing happened. I think I changed the oil again because it was a little toasted, but that was it.
Same truck had an oil bath air filter, pretty cool, always a sludge of dirt in the bottom that it filtered out. |

Still have my 86 F150. First vehicle I ever bought. Been sitting in a shed on the farm for 12+ years.
Had a head gasket leak when I bought it and when I tried to put a new gasket in found that the block was warped or something (can't remember for sure). Bought another 300 (motor only) with 36,000 miles on it and swapped motors over a couple weekends with my high-school buddies. Had it out a couple years ago after it sat for 7 or 8 years and she fired right up with a little massaging. Drove it for a weekend and noticed rear diff leak and couple other minor things and parked it again. It's on the list to get on the road again. Can't bear to sell it. Holly 4bbl card, duel exhaust, 3" lift, 33's, Ford Blue. Love that truck |

Someone out there cut up and modified 351 heads into a single head and made a straight 6 drag motor. Think there's a YouTube vid.

Quoted: I always wished they would have done a modern update of it. Aluminum head with intake and exhaust on separate sides of course it would need a turbo as well. Thing would be a tank. I had an 80 250 with the same setup. I had never driven anything that was geared so low. What was great for me was I put 35's on and didn't have to regear. Think mine had the 208 which was geared lower than the 205 if I remember right. The truck was worn out when I got it but I got a few good years out of it and wish I could afford to restore one.

I had a 2WD '76 and '86 with the 300.
I then moved up to an '86 4WD with the 300. Now I have a '96 with the 300, but its got fuel injection. Oooooh! All were manual transmissions. They weren't fast, but they had lots of torque at low rpms. You haven't lived until you've replaced an oil pan gasket on one of those engines. |

My 96 F150 was my daily driver up until a few years ago. Its out in my driveway now with 320k miles on the motor. I mainly only drive it in the winter time now since its a 4x4. Been a good truck and it still runs fine.

Had a 74 Ford Maverick with the 250, easiest spark plug change I've ever seen. Sold it to some Mexicans in Austin in the early 90's, they were taking it to Mexico where the engine would be used in a tractor.
My father had a 82 F150 with the 300, great all around truck. I never knew it to have any engine issues. Hking |

Knew a couple of guys that built a 4 door Maverick with a 300 six for drag racing.
Took a couple of 351C cylinder heads and cut them up , welded pieces together to make a 6 cylinder head out of them. Made their own intake and ran a mechanical Holley on the engine , they did all sorts of shit to it. Fucker ran low 10's in the 1/4 mile. Nowadays , some folks are doing something similar but are using GM LS heads. Attached File |
