CJ love

[turbohunter]

Got the new CJ home. Figured I do a thread on it as it will be an interesting project.
First the numbers. It is a 9C5 date coded block. C scratch on the rear. Partial vin stamp is 9H572337.
The heads are much later in the year one is a J, one is a K. The J head has a broken exhaust ear and a crack in the valve cover rail. Greg the gent I got it from has a replacement head for it. It comes with a Streetmaster manifold installed. I have been offered a CJ manifold and am undecided on if I’ll use it. It also came with adjustable rocker arms with hydraulic lifters. There are no exterior weights on the flywheel or damper. The paperwork that came with it shows balancing. It does not say internal and I haven’t gotten to the crank yet to check.
I’m waiting until I get a little farther into it before I decide what to do with it. But my initial thought is to put it in my Fairlane as I will be moving next year and it would be nice to have the Fairlane mobile.
Here’s some pics. Check out the China rail sealing.
BTW I understand about welding iron but wonder if there is still anybody out there that can fix it. Shame to lose an N head.

I would have to go look at the CJ in the 66 but that hole might not be used depending what side you put it on...I would be more concerned with the condition of the valve seats..In my experience unleaded fuel and FE heads don't mix...They are tricky to put seats in as there is not much material left if they blindly get machined out...
If HP is a goal I would leave the intake alone otherwise grab the stock one,vintage F-427 or a Perf RPM.....JMO..

 So you are bringing new CJ engine home  every another week,who gets to do that nowadays???

[blykins]

I have a guy here that can fix that head. 

Shame on whomever used the silicone like that.   And extra shame on whomever put the restrictor in, then put a helicoil in on top of it....LOL

I bet that engine would be a fairly strong runner as it sits, especially if it has an aftermarket cam in it. 

[turbohunter]

It is a sad tale I have to tell.
It is really is sad what some people will do to a beautiful thing.
Took the heads off today and was met with a few problems. Suffice to say the bottom end has to come apart. The pics will tell the story.

Pic 1 The head gaskets. One side is great the other....hmm. The good side head popped right off. The bad side head was cemented on.


Pic 2 Houston we have a problem


Pic 3 These ladies are missing their skirts. 3 of them.


Pic 4, 5, 6 There’s actually a bolt in there.






Pic 7, 8 More gorilla snot





Pic 9 Crank


Pic 10 you know

Marc -  There's no hatchet on the damper, right?  Hmm.  I'd be looking for mallory metal on the counterweights of that nice SCJ crank.  Hopefully the journals are OK. 

I've seen lots of 1968-70 cast Ford pistons with porous/ broken skirts.  (A broken skirt tab punched a hole in my old '68 Shelby GT 350's original 302  )  Boss 302 guys know this phenomenon well!

Yeah that engine was rebuilt by Mongo!  Mongo also had a very runny nose.  That stuff doesn't belong anywhere near an engine... I think you'll end up with something really sweet though, as long as the bores check OK and the crank isn't boogered (see what I said there  ).

[427Fastback]

I see what appears to be lemans rods..Thats SCJ stuff thus the previous question about the hatchet..Hope it measures up ok....

[turbohunter]

Good news on the heads.
Thanks to Tommy T, I remembered an old friend I had forgotten about. I remembered because Tommy had pm’d me and suggested them.
Valley Head Service is an old time shop here in the valley. They’ve been in business for almost 60 years. Fixing the heads is no problem for them.
And best yet they are only a couple miles from my house.
Thanks Tommy.

Those look like LeMans rods, but that is not an SCJ crank.  An SCJ crank will usually be marked 1UA, not 1UB.  You can also tell by looking at the center journal, see the 428 cobra jet web site.

Looks like whoever did that engine was thinking along the same lines as me back when I did my first 428CJ in 1980.  I hunted around until I found some LeMans rods, and replaced the stock CJ rods with those.  Added the balance weight required to the crank, no hatchet crank spacer.  Worked fine with no problems. 

Sorry to see all the issues with that engine, Marc...

[Gregwill16]

Sorry for the issues Marc. +1 1UB is a CJ crank but the balancer looks larger like the SCJ. Look and see if it the normal or the C8AE-C SCJ balancer.

[turbohunter]

No sweat with the issues guys.
Just gives me more impetus to make it right.
Here’s some more from under her dress.
Quality work going on here.

Representative cylinder/no ridges

Jay's right - I forgot about the 1UB representing the second generation "Standard CJ" crank. 

At least the cylinders look OK.  The crank can be cleaned up to look decent.  The important thing is the measurements, and I'd also recommend a Magnaflux inspection for cracks.

Overall not terrible news.  You're still way above $700 worth of stuff 


Had to add - I'm surprised Mongo didn't smooth out those bird poop welds with Bondo when he was done!

[turbohunter]

Yes sir I still feel lucky. I’m going to end up with a great engine.
It’s going to cost me a bit more though.
But the motor I gave to Gary has to be rebuilt also, though I think it’s in pretty good shape. But of course one never knows.
I’d like to punch Mongo in the throat for what he did to this thing.

Don't blame Mongo....
