You will be better off having the carb rebuilt. What you are asking for will cost at the least 1500. But most likely it would be a lot more. You’re talking replacement computer. the whole EFI set up which involves different intake manifold, air cleaner box, the fuel rail, the injectors, the wire harness, change in the fuel lines new or different fuel pump. Adding in relays, a change in the exhaust manifold. A rebuild on the carb would only be around 200. A new carb would be around the same price. But if your heart is set on EFI I would find a totaled sunbird (find one that’s been hit in the rear) and pull everything you need from that. It’s more then the car is worth. not to mention your car will be out of service for at least 2 weeks to make the changes. I have done a few Carb to Injection converstions and it's just not worth it. It's cheaper to stick with what you have.
