All the SBC's are the same dimensions, so you could easily bolt in a 400SBC, with minimal work.
You may see refernces to 406, 434, etc, SBC's, these are bored and or "stroked" motors, that require additional work/money, but don't change the outer dimensions of the block itself, you can also stroke BBC's too.
BBC's create additional work with exhaust and such, but have also been done many times in 3rdgens.

SBC = "Small Block Chevy". Introduced in the 1955 model year. Your LO3 305 is a SBC.
BBC = "Big Block Chevy". Introduced in the 1965 model year. It's longer, taller, and wider than the SBC. However, the distance between the engine mount bosses and bellhousing mount surface are the same between the SBC & BBC.
You apparently are pretty new to all this talk. So, you probably be better served taking smaller steps and working your way up to better performance. Exhaust is a good first step, including headers, larger catalytic converter, and larger cat-back exhaust system. This is something required for a 350 or larger engine, anyway, and will help your 305 now. Consider starting there.
