305 V8... 2 or 4 barrel carb? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Get the carb and a new/used intake. Pick a brand so long as it's made for lower rpm range and dual plenum. You will notice better performance even with stock manifolds, espcecially since you are running dual exhaust already. The 600 cfm is fine on a 305. Ran mine on a 307 for several years with no complaints. My only experience with a 2 barrel carb was the 30 yr old original that had a crappy rebuilt put in. Leaked and was so loose it was something that the engine ran.

Check the different parts boards. Also, check out swap meets for used ones. New ones can be had for around $120 from Summit.
