Chevy 250 refresh

[eodcoduto]

I’ve been working through this 68 K-10 and fixed the transmission so now it has all the gears again, and then with all the leaks I started on the rear main today. I hate leaks, like a kid hates bedtime, and the more I looked at this in order to do it right the engine had to come out. So it did, 72 minutes from decision until it was on the stand.
Its a 1967? 250, all stock and in good shape but well worn, so its going to get a ball hone and re-ringed then put back in. Nothing sexy but working on inline 6’s is fun.

Around 36yrs. ago I had a 69 C/10 step side with a 250, three on the tree and a 3.73 gear and it was such a great ride! Same color green too.
Yours being a K/10 and a granny 4-spd. just is that much cooler.

I drove it to class on campus while in college about once a week and I got many Fred Sanford comments but I didn’t care because my main mode of transportation was a 79 Land Cruiser that had more rust than the C/10 did.
Good times !

The more I work on this the more I like it, too bad the original 292 is gone.

Is the rear main a rope seal in that one?

Big props for keeping the inliner in there. Many would have stuffed a small block in to fix your rear main leak.

When GM changed from the old 235’s and related type motors in 1962 and introduced the “new” 194,230 & 250 motors they went with the common two piece lip style seals.

Old skool cool!

Buzzin’ half dozen! 6 cylinders are cool and easy to work on, and for a pickup that never sees anything north of 55mph it gets the job done.

I talked to the machine shop today about hot tanking the block for me and he said he has a complete 250 short block he built that the customer never picked up. So depending on the horse trading I’m leaning on that route. Saves me time and money.

I've always wanted an inline 6 truck. I like the popular ford 300 inline 6. Great torque. Don't see too many chevys with them still.

 

[eodcoduto]

I love the simplicity. They have good torque, and will last forever but they are getting harder to find since so many were swapped decades ago. Put a Holley sniper on them or a tbi and you are in there like swimwear.

Id like to have an inline in an off road truck with a 4 speed. Gobs of torque and simple and reliable. I had a 258 inline 6 in a Jeep before and you almost couldnt stall it.

I had a 79 f150 with the 300 and np435, it was an awesome combo, just had to point and idle up anything.
My current daily is a 96 f150 with a 300 and 5 speed, good mileage and torque, just all done by 3k

I have 4 of them just hanging out.

Absolutely agree !

My first 4x4 was a 79 Toyota Land Cruiser FJ-40 with a 2F 4.2Liter inline six cylinder and just as you said it was real difficult to stall it off road - it would lug-n-chug down to 300RPM’s and sound as if it had stalled but once the clutch pedal was depressed it kept on running ( probably due to the heavy-ass flywheel on those things ).

I ended up putting a 350 in it that was a blast for a nineteen year old to drive and the power level went up greatly ( as in sling’n rooster tails in the mud and goin fast in the sand dunes ) but nowhere near as strong way down low in the 1500 RPM and down range like the 2F would do.
I’ve always missed that kind of low end power band of a strong inline six cylinder engine off road.

When I was young one guy in our four wheel’n group had a dark brown 79 F-150 ( named “Doo-Doo Brown” ) with a 300 NP-435/205 combo and it impressed most all of us off road ( while the rest of us were runn’n 350’s, 351’s, 400’s and 454’s ) that motor just pulled so good down low and was reliable as could be.

 

[Big Ray]

Well, since we're talking straight sixes...

 

[eodcoduto]

That thing is awesome

Tarussel, I read you mention in the past about Chevy giving Toyota birth... you suppose 2F come from the 250 line of power plants?

Not as cool as video Big Ray posted, but some inline 6 fun. Toyota 2F with a Sniper and rusty Chevy Bow Tie on the air cleaner 'cause it's what I had.



For giggles, the mule skinner herself on the first test drive a few years ago.

That’s a cool set up !
A good EFI system really wakes up a 2F.

The Yota 1F actually had more in common with GM’s 235 type family of engines than the 2F did but there’s no doubt about its origins.

What year FJ60 was that in?

Yes it does!

1986.
