I have a 460. dont know the year or what it came out of. The numbers 5Y825704 are located on the left rear bank of the motor on a smooth spot. Thats the only numbers on the motor. I want to know what they mean and cant find any information anywhere else on the internet for them. A little help, please.

 

That doesn't seem like a proper casting number. Is there anything cast in the block near the freeze plugs? See the white painted lettering near the bottom right of the photo below... This is a 429, but, AFAIK the markings are similarly placed through the 460's.

 

Below are links to a couple places you can find decode info for typical casting numbers.

Most common 460 block casting numbers.

D1VE-6059-AB, AB1, AB2: 1971/73 429 / 1971/78 and some 1979 460's.

These engines do not use a weighted spacer.
--------------------------------------------
D9TE-6059-AB: Some 1979's, 1980/86 460.

This engine uses a weighted spacer and the flywheel and harmonic balancer are different than used with the D1VE blocks.

 

its not a bare block. its complete, kind of rusty but complete with tranny and transfer case.

 

Uh huh...

But, if you want to know what the engine is, the bare block casting number is what you need, cuz casting numbers on heads/intake manifolds won't help when you consider parts swapping.

The first year the 460 was available with 4WD and a manual transmission was in 1983, but is it a 1983 or later 460? Without the block casting number, there's no way to know.

 

I didn't know what freeze plugs were, i figured they would be on the inside but they are the outside. I'm new to this..

I made one phone call today and found out it's a 1974, 1975 smog motor their was about 2.1 million of them made and stock it has 265hp

 

The 429 and 460 blocks are identical so how the hell can you state this is a 429?

 

i got another question. since i know roughly what it is. what kind of heads should i get? ive heard stock are bad.

since this model wasnt 4wd how could i make it 4wd? would i get a different T-case?

 

Stock heads aren't necessarily bad. First thing you need to do is decide what you are planning on doing with the motor. I am guessing that you are going to put it in a 4x4 truck or bronco. How much power do you want out of the motor? Are you on a budget? Are you going to completely rebuild the motor? There are lots of directions to go with this. Your motor should have D3 (casting #) heads, unless someone swapped different heads on. These are not bad heads, especially if you are willing to do some porting on mainly the exhaust ports. Again, it all depends on budget and what you will be doing with it. If you are going to use the heads you have, you need to check their condition. By that I mean check to see if you have bent pushrods, bent or burnt valves, and if there is excessive play between the valves and the valve guides. One good thing about these heads is that they should already have hardened valve seats, so that saves some money if you have to take it to the machine shop. As to your question about making it a 4x4 motor, it doesn't matter that it came out of a 2x4 truck. I have a motor I am building that came out of a thunderbird car. My advice is to spend a little cash and buy some motor mounts for your particular swap, unless you really just want to do it yourself. As for mounting the engine to the transmission, that depends on what motor you are replacing in your vehicle. Automatic or Manual?

 

bear that block happens to be a 429 because of the stock 4 bolt main caps no 460's except for after market svo blocks came with 4 bolts.

 

Yes the motor is going in a mud truck. i want enough horsepower to move a nice set of 40's. yes im on a budget. i was planning on rebuilding it though since the motors sat for about 7 years. how would i make it a 4wd then? its an automatic.

 

Ok, what axles are you using and what gear ratio do you have in them? I would think with a set of 40 inch tall tires you would need at least 4.10s, especially with an automatic. If the 460 you are rebuilding was mated to the auto transmission and transfer case, then its already four wheel drive equipped. Its just a matter of getting it all placed in the truck. If it were me, I would have the transmission rebuilt as well. If you are on a budget then I would use the heads you have already. As to the specs of the build, your machine shop can step you through it and help you decide what you need done to your parts.
