69 - 71 MFI magstacks the same?
 

Does anybody know if the 69E and 71E used the same part number MFI magstacks. What's the part number for the 71E?

thx,

al

Hi Al -
I believe that the stud spacing on the throttle body / stack interface was different. 69 had one spacing and 70-73 had another spacing.

That said, the stud spacing on the heads was the same so you could use a complete 69 throttle body/stack setup on a 71 or vice versa.

Andrew,
thanks. Do you know of a source that lists the part numbers?

You can tell the 69 stacks because they are the only year to use a 901 pn all the later ones had a 911 pn.
