engine dimensions

Are 429's and 460's the same physical size? In other words, can they be swapped without vehicle modification?

Which one would be better for average street use in a Ford F250?

Thanks, j84b

Yes they are the same size.

Yes the can be swapped, but their are some differences.

Later EFI engines are not a direct swap for earlier carbed stuff. And the heavy truck engines have a lot of specific differences too, that will not allow a direct swap.

Thanks for your interest, but I cannot see any relation between this reply and my original question. j84b

I think Jonesy meant to post that in another thread.
