Advice on my "stock" 340 build

Hope everyone had a great xmas, ive been thinking about sending my carb out for a restoration for this stock 340 build, i have 2 to choose from and not sure which one would be better
1. 1969 4611S Which is the 69 4-speed carb...or
2. 1970 4937S Which is auto w/ecs.
any help would be appreciated, right now im thinking about these 2 and not buying a brand new carb, your thoughts?

Also im thinking about taking RRR advice and use an OEM ignition system, thinking about the 72-73 electronic unit, maybe our resident distributor guru can set me up with a whole kit, distributor, harness,ballast resistor and a ECU (what color box ?)

Thanks for reading and the help, all suggestions are welcome...Rich
