I was doing research to turbo or supercharge a car I have.
You are better off using draw thru on a supercharger.
you could mount the charger on the drivers side and plumb it over.
you wouldn't have to do any radical changes to your carb.
to pressurize a carb, there needs to be alot of internal changes.
if you draw through, your vacuum system would stay the same.
you'll need the MSD6A with boost timing retard and a bypass valve.
You may want to double check but I thought the supercoupe came with the eaton M62.
They are always on ebay
