Re: IML: 413 vs 440 in a 64 Crown

["Pete Engel" <peter.engel@xxxxxxxxxxx>]

There is no difference in external dimensions between a 413 and a 440.  If
the guy who installed the 440 used all the 413 manifolds, oil pan,
accessories, brackets, etc. then your swap back to a 413 will be a breeze.

If, OTOH, the 440 was installed used all the manifolds, etc. from the 440
and it was a much later engine then you will have some heartburn.

Why bother removing the 440 to put in a 413?  The engines look identical
from the outside.  Is the 440 shot and you'd rather have a 413 under the
hood?  Is the 440 a late production, low compression engine?

Hey all you mechanical experts,

What would one need to do to change out the 413 in a 64 Crown to a 
440?  What things would need to change/be replaced etc.  I am not asking 
this because I am contemplating doing it, on the contrary, I am thinking 
about undoing it.  A previous owner did this to my car, and I am wondering 
what it would take to undo this and put a 413 back in.  Would I need to 
replace all my accessories like the alternator, AC compressor, starter 
etc?  How about the radiator?  Would it just be a matter of pulling out the 
440 and dropping in the 413, or would I need new motor mounts (I may need 
them anyway).  How about the transmission, would anything need to be 
changed there?

Thanks for your input,

Mark Elliott
