normally I'd say 350 or nothing but we got a little 305 that sure made a beleiver out of me. It came from dad's 84 c10 and it's now in the 85 mcss I sold to my brother in law, and it ran awesome in the truck for a 2.73 rear gear and it'll smoke the tires as long as you want it to in the mcss with 3.42's Both ran th350's and the monte has a stage 2 shift kit and barks tires hard going to 2nd and can get some chirp going into 3rd. I ran a 350 in the mcss when I had it and it's now in the 84 c10, and the mcss does better with the 305 in it, however I had a 2k stall in it before with a 350 and it would barely break em loose, I think I got a junk converter. Now with a stock 305, just long tube headers and an edelbrock with a stock tc and that stage 2 shift kit th350 it screams as mentioned above. I aint rode much in the truck with the 350 in it now and a stock TC so I aint sure how much better it seemes to run now compared to when it had a 305.

I do know that same 350 in a 76 that had posi and stick shift it was nasty, you couldn't keep it from burning tires off, but I think it had a good ratio like 3.73 or 4.10 or so.

I think I'd stick with a 305 if cash was tight, rebuild and maybe torquey cam and intake and maybe carb swap with headers, if not and you can get a donor with a 350 go for it and as said build another truck or part it. I'd buy a parts truck put the 350 and any other good stuff on yours, put your junk back on it and sell it whole.
