I have a 79 ford F250 4x4 that I was told by the seller had a 429 1969 ford country squire motor in it. The heads have a casting number D3VEA24 Or A2A can't really tell. What motor is this. The valve cover has a sticker on it that say's it is 460 family. Thank you so much for any imformation you may give me on this. Don

 

460/429 are the same motor the 429 is a stroked motor either way you got a good motor...
the 429 is supposed to have more snap off the line where the 460 will get you in the end...

 

Welcome to FTE!

That guy is lying to you.

That engine you have was designed for an first cast in 1973 for a Lincoln or T-Bird

The 429 was last cast in 1972.

If it has 7 valve cover bolts
That is an Full of emissions stuff 460.
That A4A is a dead give-away for numerous changes to the part.

You need the actual date of cast to see what year it is.
Gets the cast dates from the oil galley of the heads.
Look for something like this *5C22*

If it doesn't have 7 valve cover bolts,let us know

Sorry, No 429 for you

Also,
You probably noticed this thread was moved.

An engine Specific (Engine Ident) question is not for a YEAR of TRUCK specific forum.

 

And to add to what Dennis said, I think your backwards, A 429 is a destroked motor. A 460 would have better torque off the line, due to the longer stroke, and a 429 would get you in the end, due to a higher RPM capability, is that what you meant?

Your really almost comparing apples to apples here anyway, year of cast is far more important than CID.

I think one of my first posts on FTE was in here asking pretty much the same Question, and the same Administrator, with the same unforgettable avatar helped me too......ahhhh the memories.

get those cast dates and get back here......

 

Well you guys missed one point he may still have a 429 even though the heads are D3 castings, someone could have swapped latter heads on to lower comp to use the lower octane fuel, or someone rebuilt it at one time or another, and the machine shop could have been less than honorable, and kept the better early heads, and gave them back the latter smog heads.

 

Hey Monster,

I tore a 429 down yesterday that had D3VE-A2A heads and a D1VE-A2B block, the crank and pistons were 429. The engine had low milage but sat for years in a mans garage and was froze up, it did not even have any ring groove in the cylinders and when I removed the intake it was clean. The bore is standard.
Now could these heads been stock on a 429.



David

 

no, not possible based on the numbers, 429s were done by the time those heads were conceived.

 

So witch year was the 429 retired, 1971 or 1972?

 

David, I beleive it was 1972, as in they were actually cast in 1972 also, and the date for the heads was 1973, that was my logic pattern there....

 

Kevin is almost right, the 429 for pass cars, and light trucks was disontinued in 72, the medium truck version was built into the 90s, but it had the larger harmonic balancer, bigger crank snout, and a steel crank ( I won't say all the time cause we have all seen ford do some strange things over the years) the D1 block and the D3 head combination was used from 73-78 when they switched to the D9TE blocks for 79. So the answer is no those should not have been the stock heads on that engine unless it is a medium duty truck engine, but was probably switched do to the detonation problems with the 72 heads.

 

The 429 was available in full size cars in 73 but not the thunderbird or lincolns. I have seen many over the years. They all had D3 heads. The change over was done in late 73 when the passenger car 429 was done away with.

There is no 429 or 460 specific passenger car head as the same heads were used on both. The CJ and PI castings are another story though.

Earlier 429's had flat tops with 2 eyebrows in the passenger cars. The 72 and 73's has a shallow dish in the piston shaped like the 460's just not as deep.

 

Well there we go, mystery solved I guess.

 

Okay guy's here are all my casting numbers The rods are C98E-6210-B The crankshaft is 2YAB The block is D1VE A2B and the intake manifold is D4VE.. Can you help me figure out what this and if it is worth rebuilding. It is going to need a reground crank for sure and I fould a crank kit with all the bearings for 229 dollars. Thanks for all your input Don

 

The I.D. number for the crankshaft suggests a 460 according to the book I have.
