Should have been aware of your ability to multi-task. sorry!

Who says I can multi task??

Raffin!!

I've been known to smile AND nod when the woman's a jabberin away...

Mad skilz yo....

You get parts yet Foo?

UPS tracking says Wed.

Did Ford produce a hi-boy with a Perkins diesel in the 70's?

Not that I've ever heard of but that would be awesome huh?

I kind of think most were 360 FE's with a mixed and debatable population of 390 FE's as well, 300 cubic inch straight 6, and then the oddball half year M block highboy like mine. The 77 model highboy was the first to get the 400/351M engines. And late year 77's were said to be "low boys"

Mine is a 77 model built in 76, so I have the odd duck M block Highboy. Which is kind of tricky to buy headers for. Highboys were narrow frame trucks, so early year 77's were the only 400/351M block and narrow frame combo.

So, header applications are... complicated

Any idea why the frames were narrower? How much? I didn't know that. Good to learn something today.

The "low boys" weren't much lower IIRC, as they're still 3/4 ton rigs right?

I can see where headers would be tricky becasue they don't fit that great to start with. Chassis exit would work, but a little radical for what I think you're looking to do.

The term "highboy" was a consumer nickname given to the trucks manufactured for a period of time that shared chassis, drivetrain, suspension combinations.

Divorced transfer case, arched front leafs (look like a smile instead of a frown), the narrower frame rail spacing and a crossmember at the very front of the frame behind the front bumper are all indicators of a "highboy"

mid year 77 model they married the T-case to the trans, went with the different frame, negative arch springs up front.. I've heard varying opinions as to the difference in height between highboy-lowboy, anywhere from 2" to 4".

Yeah, that's what I'm finding too. What I can't find, unless I'm reading it wrong is the frame being narrower. I did find the springs were narrower, probably to "arch" them better? I don't know... It's fun finding the info tho.

Now that I've seen a bunch of pics searching, I want a 67-72. My favorite body style of Ford trucks anyway.

33.5" frame width I believe.

wheels, tires and exhaust come today!

I'm not aware ford ever selling trucks with the Perkins diesel, but I've read that the diesel from the Massey Ferguson 750 combine is a feasible swap. There was a half ton with one on craigslist a while back.

35's

I'm silly with the happy.

Gotto go back outside and hang the dual exhaust now.

Hang that exhaust dave....rev it up, rev it up!

Looks aweseom - needs a scrubby buck rack wired to that front winch tho - boss hogg of MN....

the exhaust is a kit by hooker headers, said to fit this year truck in half ton and 3/4 ton.

Not!

I've had to cut and lengthen, shorten and rotate angles in a few spots. Lots of cutting, welding, test fitting etc.

I guess I don't mind turning it into my own custom exhaust but I wish I would have known it wasn't going to fit, I would have just purchased a munch of 2.25" pipe and elbows, sweeps etc.

Oh well, I have it from the manifolds to the new turbo mufflers and wow does the truck run better. That old single muffler was really plugged up. Must have came apart inside from rust and everything.

Overall, a really good night's work.

If you'd quit buying trucks, you wouldn't be "po" any more.......

very true.

these old trucks are like a "free puppy"

we all know there's no such thing as a "free" puppy.

And we all know you can't pass up either!
