The 240 Inline 6 Went "Poof" In my '69 F100 Ranger

About a month ago, while on my way home from work, the 240 in my truck puked the #5 piston, punched a big hole in the cylinder bore and a hole out the left side of the block.

I found a 300 L6 short block in the wrecking yard to replace the 240 with. The following link is the saga detailing where I am up to this point of nearly being ready to fire the 300 for the first time.

Ultra, I am interested in your story, but when your linktakes me to the truck forum, a very suspicious “award” script takes over the thread. Just for giggles, I tried it three times to see if it would time out, but it persisted. The prize award is obviously a scam that I do not want to participate in. Do you guys have a lot of problems like that on the truck forum?

Your link works for me with no issues, very interesting build. Congrats, please post more of the progress here, instead of looking at the other forum.

That was a good read and very nice work.

You get a good star for being able to kill a 6 cylinder, I haven’t seen that very often.  And that hole wasn’t that big!!  How long have you been holding onto that “ best pizza on the block” ??

Not sure what browser you use, but Chrome and Firefox have some nice ad blocker plugins. Ad Block is my favorite. A lot of those little banner ads websites run can have some nasty programs in them.

That's never popped up anytime I've ever been on the site.

This forum does not play well with my phone when trying to post pictures here. On FTE (Ford Truck Enthusiasts) posting photos isn't met with complications.

Maybe the 300s are more bulletproof than the 240s. I can stick two fingers through the hole in the left side of the block and I can put my fist in the hole in the cylinder wall.

LOL on the pizza.

Thanks. A lot of work and time has been put into it over the past several weeks. I'm ready for it to be done just so I can relax for a few days.

Wow Steve - nice work. You and Hakan set the bar for Excellence in Automotive Restoration! Hope your rebuild goes better than the 250 I originally installed in my 68. I spun a rod bearing at 600 miles - best thing that could have happened. I pulled it and installed the 351W.....

Re: The 240 Inline 6 Went "Poof" In my '69 F100 Ranger

Nice work, as always, Ultra!... But weren't you planning to put an EFI 5.0L in this truck?  Wouldn't this have been a perfect time to build that?  No criticism intended...just curious.

You are correct. I can either install a '90 Mustang GT 5.0L engine I have or, fuel inject a 351W I also possess. The problem is, I don't have everything I need to install either of those and the 351W would require even more parts to make that happen --and is likely the one I will eventually put in the truck.

Since I wasn't planning to change engines at this time, the funds weren't currently available to be able to do that. I thought when the time came to take the six cylinder out, it would be to replace it with a fuel injected V-8. I wasn't planning to swap a six cylinder for a six cylinder but, that's just the way things went because the majority of things were there to put a six cylinder back in more quickly and less expensively than trying to swap in a V-8 at this time.

While it isn't exactly what I wanted and when I wanted it to happen, I will be getting roughly a 66 cubic inch bump with the .030"-over 300, compared to the 240 it replaced. The 300 is power house in the torque department and 66 more cubes will definitely be noticed.

Ultra... You have GOT to QUIT racing those Corvettes with that truck!

I think that 300 is a great replacement and will make a great truck, just as it is.

Somebody's gotta beat 'em! Ha ha.

After tying up some loose ends on the engine this morning, I fired the new 300 for the first time --even took it for a drive.

--Just realized I had a Mustang Steve Tee shirt on too.

Thanks, Michael. I'm glad the assembly of the engine and getting it running are finally behind me now. I have to take it this week to get the dual exhaust run. After that, the danger Ranger will be back on the road again.

Re: The 240 Inline 6 Went "Poof" In my '69 F100 Ranger

Sunday a week ago, I got the new inline 300 running in my '69 F100 Ranger. The exhaust system was run on it this past Saturday and I picked the truck up from the exhaust shop Saturday afternoon and drove it home.

So far, it runs really smooth and strong --MUCH more low end torque than the old inline 240 that was in my truck. 

I drove it to work this morning for the first time since it went down 6 weeks ago. I had a minor issue but it wasn't with the engine.
