Daily driver suggestions.

Hi all, I'm working on upgrading my 1970 valiant to be a more comfortable daily driver. (Slant 6 225 with only 12000 original miles)
To that end i'm looking for specific suggestions around the ignition and carburetor.

I'm thinking upgading to electronic ignition, and possibly to a throttle body. With the goal of improving gas millage and throttle response.

Does anyone have specific model numbers they could suggest?
Thanks
Mike
