The 330 HP crate motor may carburated. See if that is so.
If you can live without matching numbers and such, 330 HP and a 700-R4 sounds like a nice combination for a "driver."
Try to have someone who knows C3 bodywork put thier hands on the car to see as many issues as can be found.
I like the look of the '82 Collector"s Edition. That, 330 Hp and an OD Trans. could make for a nice "driver."
Let us know how this goes.
