       I think you need a new manual.   What manual do you have anyway?  It 
sure is wrong.
       The I mark is indeed about 80 degrees Before TDC.  The Haynes manual 
for the Alfetta says to align to the P or TDC mark on the firing stroke.  
Both valves should be closed and the cam lobes for number one cylinder should 
point away from each other.
       Then it says to turn the crank pulley anti clockwise or the reverse of 
normal rotation to align the I mark.  Then align the marks on the Spica pump 
and put on the belt.
       It sounds as if you got it right.

       Just as a matter of interest, I looked at the timing marks on the 74 
GTV in my garage.  Starting from the P or TDC mark, the M mark is about an 
inch to the right.  The I mark is another inch and a half further down to the 
right.  The F or static timing mark is about half an inch to the left of TDC.
       All references above are from the perspective looking at the front of 
the engine.  And measurements are estimated.
