429 crank in a 460?

Post  Stevie95 on October 12th 2013, 7:17 pm

hey fellas first post here also first engine build and need some info.
I just got my 460 today which turned out to be a 429 out of a 70 Lincoln. when we got it out of the rubble I noticed there was a chunk missing where you bolt in the water pump. Instead I just got another 460 bare block and took off the crank and pistons off of what I thought to be another 460 and took them home. now that I have taken a closer look the pistons say 429 and I am assuming the crank does as well.

I was wondering if the crank from the 429 will fit the 460 I have now and will hold up as well as I here the 460 stock cranks do.
also I've looked around on the sites and read the429 pistons will stick out of the bore please correct me if I am wrong
Thanks.

Unless you are talking industrial 429 with the bigger snout any stock 429 crank will fit in any stock 429/460 block

conversly any stock 460 crank will fit in any stock 429/460 block.

There are some 460 cranks that require the hatchet weight to achieve proper balance and in rare instances the newer long bore blocks may need to be relieved/massaged.

All the connecting rods are interchangeable (same length) except for the really weird Nascar 429 shotgun stuff.

The pistons you use have to match the crank.

460 pistons on a 429 crank will fit, motor might even run but it would have very low compression... it would be a dog.

429 pistons with a 460 crank would result in the pistons coming out of the bore by a ton and the engine would not turn over with the heads on.

Keep reading

Lots of good info here.

As long as you use the crank from the 429 you will be good is the 460 block a DIVE if so the 429 crank will work but if it is a D9ab it will take some machine work to make it fit in the d9 block

If it's a 3.85" stroke 460 crank and pistons, it's a 460 cubic inch engine. If it's the 3.59" 429 crank and pistons, it's a 429 cubic inch engine.

429 and 460 uses the same block up until 1979
