Gentlemen:
I've thought about putting my old Nova's 305 in a Cutlass (1980). Will it fit and, if so, any special mods I will need to make?
Jack.

Jack.
What motor did it come with?
1979 might have had the dual bolt pattern TH-350 because it was the last year of Olds starfire was manufactured. Its V8 version had Chevrolet built 305 and TH-350. This also made possible to get almost any Olds with 305 as a dealer option. At 1980 this wasn't possible anymore and it's not likely to own a 1980 Th-350 with dual pattern.
Anyway I would give an effort to replace 260 with some "nickel free" 305. If you want it light get a late model Olds 307 with roller cam and a _good_ carburetor. If you want it to grunt get an Olds 455 and machanic double pumper carb. It will fit very easily even with A/C. In the 455 case you might want to change the front coil springs to heavy duty springs too ;)
