How do you ID a SCJ 429? I might have a chance to buy a 1978 Bronco, from a friend, he said it has a SCJ 429 in it. Also, would the rear fit a 68 fastback, I'm thinking it should be a 9". Thanks for help------------------

An easy way to identify the CJ/SCJ heads is that some of the valve cover bolt holes go all the way into the intake ports.
So if you remove the valve cover bolts next to the intake manifold, the engine should begin to run like crap because of the vasuum leak through the valve cover bolt holes.

Bronco rear should fit with nothing more than some simple spring perch relocation.
A few more SCJ ID tips.
Holley carb and flange on the intake.
Push rod guide plates and the rockers should have a lash since they have solid lifter cams. Cast aluminum valve covers too.------------------

"D0OE-R" casting number on the cylinder heads. It's visible just below the bottom edge of the valve cover above the exhaust ports right in the middle of the head.The heads are the most valuable part of a CJ/SCJ. If it has any other heads it's not a CJ/SCJ. The other desirable heads would be police interceptors "D20E-AB".

Those heads, as well as the CJ/SCJ heads have 14mm spark plugs (5/8" socket) as opposed to the garden variety 385 series heads w/ 17mm (13/16" socket) plugs

The CJ heads have bigger valves & ports, plus adjustable valvetrain. As for the rearend, the Bronco would have the large 5 on 5 1/2" truck bolt pattern, so car wheels wouldn`t fit. I would also think that the rear would be wider. Considering that every 69-70 Cougar came with a 9", it shouldn`t be too hard to find the right width 9" for your car.------------------

Be advised CJ/SCJ and Police Intercepters are few and far between, so don't get your hopes up too high! The names are easily tacked on to plain 429/460s in hopes of driving prices up! So check those part numbers, maybe you'll get lucky
Good Luck!

Actually, if it is an early block under those heads it is very desirable too. If you decide to toss the block let me know. Early model blocks are getting harder to find.  If you look at the main web area they seem to be a little bit thicker in some places over later model blocks.

The only way to tell if it is a SCJ block is to drop the pan and look for the four bolt caps.------------------

The 78 Bronco rear is not a good choice for a car, the width is a BUNCH wider and the pinion is offset to the right. The 5 on 5 1/2" bolt pattern is a problem too. The Early Bronco 66-77 is narrow enough, but the wheel pattern, pinion offset, steep pinion angle (makes the brakes aim downward when you correct it for a car) and almost everything other than the gear ratio makes it unsuitable.The SCJ heads are the important bits, the 4 bolt block is hard to discover in the truck, but casting numbers can rule out blocks that aren't SCJ, it should be no newer than 1971.

Is that true for all SCJs? I learned that a small number of CJs came with two-bolt mains.

Everything I have ever heard is that all SCJ's were 4 bolt mains but some of the early CJ's were 2 bolt mains.

The problem with telling a 4 bolt main block from a 2 bolt main block is that the part numbers are the same. The only way to tell is to pull the pan.You're probably going to see part numbers of D0VE or D1VE on the block but that won't tell you anything. There were both 2 bolt and 4 bolt main blocks in both these part numbers. Generally all 429SCJ's are 4 bolts and all 70 429CJ's are two bolt. Then in 71 the 429CJ's are 4 bolt. Also the D1VE blocks were used into the late 70's, so that part number doesn't tell you much either. That's why I said look for the head part numbers. The shortblock you won't know until you tear into it.

I talked to my friend last night and he confirmed that the motor is indeed a SCJ 429. The block has 4 bolt mains and uses 14mm (5/8 wrench) spark plugs. Also if you pull those bolts, you will have a bad vacuum leak. Was not able to get numbers off the heads though. He did say that the motor had been sleeved in 1 or 2 cylinders. With this known, what do you think it is worth?

How much do you think I offer him for this Bronco with the SCJ429? The Bronco has a lot of rust, I would only really buy it for the motor. I could sell the rest of the drive train. So what do you think?

I know a guy who sold a 429cj 4 bolt main complete engine on Ebay a while back and it sold for $1500. He had offered it to me for $1000. That would have been a good deal but at the time I was in the middle of building my new engine and couldn't spend money on another engine.

That sounds about right to me. I think I'll offer him $1000 and see what happens.
