4 cyl big block!

[steve ravet]

So, I was crawling around my boat ('81 Phantom I/O) w/ Mercruiser trying
to find out what kind of motor is in there to give me some hints on
converting to EFI.  I found a casting number on the head, D3VE-A2A. 
Tried looking it up in altavista and guess what? I've got a Ford big
block in there!  Don't know how they got 460 CID out of just 4
cylinders.  Or maybe I just missed the other 4 cylinders.

Can anyone help me figure this out?  Here's some other info I found:
Model #:   MCM470
disp:      224 CID 4cyl
170 HP

The dist and the oil filter are both on the right/starboard front of the
engine, the filter is horizontal.  What is it???
