Go to the "feature Cars" section and read a very similar article...it is about an
EFI conversion on a Pantera. It was a little tricker then yours, since there never was an EFI application (production in the USA), however, based on horsepower and parts needed, it should be as close as you can get without someone holding your hand.
Yours will be easier, since you do not have to fabricate the intake manifold, otherwise it should be a slam dunk.
