I just purchased ( at least what I thought) a 429 out of a 68 t-bird. The casting #'s on the block are "C9VE-B" and the head casting # is C9VE-A. From the information I have found on the net it seems this is a 460 out of a 1969 Lincoln Continential. I cannot find anywhere where a Lincoln was available with a 429 in 1969. Can anyone confirm this for me?

 

the 429 and the 460 are the same engine, its just the 460 has a longer stroke!!

 

You, my friend, have one heck of a good starting place for a street build!

The casting numbers are right for a 68-69 vintage car. Chances are it's a 429. If you are lucky there is still a little metal tag under the coil hold-down screw that tells you what it is. If not, pull the pan and look for the casting numbers on the crank. If memory serves a 429 casting number will start with 4U and a 460 casting number will start with a 2Y or 3Y.

if memory serves me right fords had the 429's back then and lincoln's had the 460's

 

Thanks for the replies. Unfortunately the tag is gone from under the coil. I will pull the pan and find out what the crank casting number is. This is getting exciting, as the guy I bought it from had no idea what it was out of. Late sixties big block = very happy new owner.

Be sure to check all the piston skirts. The 429 skirts have a nasty habit of cracking.

An easy upgrade would be to locate a 460 crank. That way when you need to bore it (if it doesn't need it already) you can use the crank for your rebuild. The extra cubes will be 30 or so free horsepower.

If it is a 429 and if you do buy a 460 crank later you will need new pistons as the 429 pistons will be out of the block with the 460 crank. The rods are the same size for both but if you plan on building it for much racing I would suggest aftermarket rods as those are usually the weak link. Not trying to scare you, it really just depends on your intended use of the engine. The 69's from what I've been told do have good blocks and heads though.

 

I do know that the 429 came in the 69 and 70 T-Birds, and like I had said before, the C8,C9,D0,D1 blocks are highly sought after as are the D7,and D8 truck blocks as they can take a bigger bore (so I have been told) and there a 4 main...

i could be wrong but i always thought the only 429/460 block to have 4 bolt mainsfromthe factory was the scj?

 

From what I understand the Scj and Cj did not ALWAYS have 4 bolt mains,but most did...

 

what is a 69 thunder jet worth?
