Need opinions on carb vs efi

[encasedmetal]

Hi, I just bought an 85' C10 SWB with a 305/SM465 4sp trans for a daily commuter. I typically travel 60 miles a day and some of it is in heavy traffic/mtn roads. I am currently making plans for what I want to do to the setup and split between throwing a new 600 carba nd aluminum intake on the 305, or putting a FAST efi with aluminum intake on. My main concern is reliability and cold starts- as I'll be driving this everyday even in the winter and I need to get to work. The other option is to LS swap it, but I would have to be very organized and knock the conversion out quick and conservative budget wise (<5K total). What do you think I should do? I've never owned a carbed vehicle before so it's all new to me, which is funny since I tune efi.
