I have a VERY NICE rebuilt 460 or 429 engine...But i am not sure which, grin...It has D9TE-AB on the block also i see GP 82859 on the block, intake manifold says C8SE-9425-B DATE CODE IS 8A19, HEADS SAY D3VE-AZA and DATE CODE IS 5C31 looks like..Thanks for the help, if any other information is needed just let me know where to look..Thanks alot !!!

D9TE is a late 460 block. 429's weren't made that late. One way to tell would be if it has the external balance weight behind the balancer it would be a 460. Only other way would be to drop the sump and check the crank.

Or very carefully measure the stroke using a piece of wire through a spark plug hole, as you turn the engine over by hand.

The 429 crankshaft will NOT fit into a D9TE block (without modification) because that block was revised and used from 1979 through the end of 460 production. The revision included extending the cylinders deeper toward the rotating assembly...so the pre-1979 429 and 460 cranks will not fit. Since the 429 ended production long before that block was made, it is not possible to have a 429 crank that will drop into it. So you must have a 460 bottom end (unless the block was modified to accept the 429 crank--highly unlikely).

You D3VE-A2A heads are a 1973 engineering revision head; your particular heads were cast in 1975. Your intake manifold was cast long before that. It appears as though your engine was assembled from various year 460's. Not necessarily a bad thing.

Other ways to evaluate whether you ahve a 429 or 460:

One way is to flip the motor over and unbutton the pan. One of the crankshaft countrerweights has alphanumeric markings stamped on it's edge, and these markings identify whether it's a 429 or 460 crankshaft.

429 = 4U, 4UA or 4UAB

460 = 2Y, 2YA, 2YAB or 2YABC....or 3Y or 3YA.



Also, for quick identification of the crankshaft, you may look for the nodule or embossment between the first main journal and counterweight. The 460 is embossed there, while the 429 is not:

429


460

So I am in the same situation. And I guess the answer is that therer is no way to easily tell which engine you have without pulling it apart!

I am looking at what is supposed to be a 1971 Lincoln 460 engine but I am sure mods were made over the years. I can look at the casting number but all that will tell me is what year and what model the part was made for... like D0VE ( I don't think that therer was a D1VE part).

How can I be sure it is actually a 460 engine and not a 429? or some other similar sized V8?

Well, 429's and 460's use the same block, heads connecting rods, carburetors (the 4-bbl's), intake manifolds, exhaust manifolds, distributors, timing cover, etc. Basically everything is the same except the crankshaft and the pistons. So the best way to tell for sure is noted above.

I'm also trying to identify my crank. By Paul's pictures above, it is a 429, as it does not have the embossing, but I can't find the relevant stampings on the edge of the counterweights. I do see some numbers: 16 and I5 (not 15) on the first counterweight, plus a tiny stamping that reads something like '11J' but it's hard to tell as it's so small. I can't see any other stampings anywhere else on the crank.
Perhaps I'm looking in the wrong place - any suggestions?

Thanks!

Try the 3rd counterweight down from the snout, along the leading edge or trailing edge of the counterweight...not on the radius of the counterweight. You should find a 4U or 4UA...might be covered in grease and grime, so look closely.

and there it is... the weakest stamping I have found on the crank! Barely visible in fact. Only 1 bar of the U is clearly stamped, the rest is partial at best... a bit more searching and I could see part of the 4 but that is it.
I would never have found it without the help, thanks Paul!

Hello i am from the Netherlands, i just bought a cobra with valve covers displaying Cobra 460, but i need to know from what year it is and is it a 460? The numbers on the block saying: DIVE-6015-A2 Could someone help me out?
