Re: 404/446 generation engines and their exchange

["Ryan Moore" <baradium@xxxxxxxxxxx>]

If you did swap that MV into your 1210 you would be one step ahead in a
7.3L swap, since the 7.3L is uses an MV block.   I thought that the
bellhousing for the MV engines was different than the SV series, but I'm not
sure about that.

I think 446 was as big as the MV got, and IIRC that is also the displacement
for the 7.3L diesel.  I don't remember if there is a CID between 404 and 446
or not for the MVs.

> I have a 446 V8 which is the same engine family as the 404 which was used
in heavy trucks. It has crossed my mind today while taking the bellhousing
off....would it be possible to put one of these in place of a 345/392? The
bellhousing pattern looks the same. I am still debating what kind of engine
I want to put back in the 1210. I wanted to put a 7.3 diesel in it and still
may do that eventually but I'm still fishing for input and ideas at this
point. I don't know the characteristics of this family of engine if they are
any heavier built inside than the earlier engines or what. I know there are
a few performance parts available for the early engines but surely not for
the 446. Perhaps a custom grind cam might be a possibility.  Does anyone
have any ideas?
