Your car runs on a computer. The computer is fed info from all the various sensors and then with that info the computer sends signals to your carb to meter the proper amount of fuel and to the distributor to provide the proper timing advance. The carb, distributor, computer, and all those sensors work as a set. It will not work right if you eliminate even just one of those components.
If you want to de-computerize your car then you must change the carb AND the distributor. If you want to go that route then you need to ask yourself what exactly it is you're trying to gain because I assure you swapping out your current carb for an Edelbrock ( and a differnt distributor to complete the swap ), you will not gain anything.
The computer also controls converter lockup. It does not control overdrive. Without the computer you'll have to use one of the various methods to control lockup or just run without using the lockup ( which I don't recommend ).
My advice is to tell you to just keep what you have. You're not going to gain anything by dumping the computer with your current engine. Even if you wanted to de-computerize your engine for some reason ( like gearing up for a future killer engine swap ), then go with a Qjet. The Qjet will bolt right on and fit exactly like your current electronic Qjet. The Qjet is just a better carb than an Edelbrock.
