Hi Nick,
Fitting the HEI requires grinding the intake manifold to 
clear the larger diameter of the HEI and using the 
torkshead screw from a Buick V6 ('76-'87) in the manifold 
bolt hole adjacent to the distributor.  A socket head bolt 
may also clear.  Only the Buick 350 (and maybe the Buick 
455) distributor '76-'80 will work and the distributor 
drive gear/oil pump drive dog from a Rover distributor 
 from a '76 or later SD1 or Range Rover  type engine must 
be fitted. You have one of these in your parts car. 
  Remove the roll pin from the HEI.  Grind the tang from 
the bottom of the distributor shaft (HEI).  You may also 
need to drill the roll pin hole in the shaft larger to fit 
the SD1 type drive gear.  You can use a Buick V6 HEI, but 
the reluctor (and of course, the distributor cap) must be 
changed to the eight cylinder type.
