Not overly hard to do.
What you'll need:
A manifold. Redline make these ready to go to suit sidedraughts for Big and Smallports
You'll need to thread the injector ports, and block them off
You need a low pressure fuel pump,and regulator (around 4psi)
Then you need to think about the ignition setup. Couple of options : A brand new distributor made to suit with centrifugal advance, or use the standard distributor with this
and then playing around with setting up the linkages.
I'll post up some pics, any more info you need?
