i picked up a big block ford about a year ago from ebay and is said to be a 429 super cobra jet

can someone tell me if this is true

the head numbers are DOVE-C

the block casting numbers are DOVE-A

it also has the stock aluminum valve covers and the intake is a 4 barrel intake

there are also guide plates on it as well

if anyone needs more then ask and i will tell

MrPbody

All SCJs (429s) had solid lifters. Does yours? They also had an aluminum intake manifold on some. A friend had a '70 Cyclone GT with one in it. My '70 Judge could outrun him for 1/4 mile and about 20 feet. He would hit high gear right at the traps, and would run away from the GTO after that.

well this 429 has a cast iron intake not aluminum i thought only boss 429's came with aluminum intakes

whats really confusing with this engine is it came from australia in a 70 mustang

don't know if this true though a lot of people have told me when they look at that its a 460 but any ford guy can tell its not even looking at it from 20 feet

is there any other way to tell its a SCJ with out taking it apart?

The part number "D0" is correct for 1970.

Take the pan off. The only difference between the SCJ bolck and a regular 429/460 block is the SCJ is machined for 4 bolt main caps on the #2,3 and 4 bearing saddles.

Also, measure the stroke, A 429 has a 3.59 inch stroke, and the 460 has a 3.85 inch stroke. There is no other easy way to tell the difference between the two displacements.

Are the heads on it?
If you look at the heads, the exhaust ports are perfectly oval on a regular 429/460. Both sides of the oval opening are straight. However, the SCJ heads have ports that are more rounded. The are oval, but with rounded (not straight) sides.
Also the SCJ heads use tiny spark plugs. The regular 429/460's use quite large spark plugs.

I got this info from http://www.429mustangcougarinfo.50megs.com/. I have a 1970 Torino 429 CJ-R but I never looked at the casting numbers. This info is for a 1971, but I'm guessing it is the same as a 1970.

Correct 429 CJ/SCJ Block Casting Numbers

The 429 CJ/SCJ engines used in the 71 Mustang/Cougar had either a D0VE-A or a D1VE-6015-AA block. But here's a special note about the D1VE block part numbers - CJ/SCJ D1VE blocks have the "D1VE-6015-AA" casting number while base blocks have only a "D1VE-AA" casting number without the -6015- in the middle. This appears to be a screw-up by the factory! D1VE-6015-AA is supposed be a CJ block (since we have seen more as CJ than non-CJ), but due to the info we have uncovered (click this thumbnail photo: ), its best to verify first if the block is a thin or thick web before deciding if it is a CJ. See the two photos below for examples of this;

well so far without ripping the engine apart (coming close to doing it though) i think the block is a scj but the heads are confusing me now they are D0VE-C

one other number i got off the engine is on the intake manifold it reads D0OE-9425 and the last number or letter is ground off

does is change any of this if the engine came from australia?

72' Stang 351 H/O

Well aluminum valve covers means it's something high proformance. Why my dad owned a 70's country squire with a 428 Cj in it. Best sleeper car ever.That had aluminum valve covers so you may just have something there.

Hmmmmm.............I get the impression the old threads are the most interesting.....
This is valued input, but please not this thread is almost one and a half years old, and has run it's course.

Please do not revive old threads; it just annoys other members, (especially me, since I has just about to formulate an answer, then noticed I had done so 17 months ago...)

If you wish to discuss this issue further, please start a new thread. ty.

Thread closed.
