Now that i knwo that a 307 is a 282 block, what does that makje a 305 besides 2 cubic inches smaller? And can you bore a 307 to a 327? And it was mentioned that you cna bore a 307 to a stock 350 so i assume you can make it a 355 as well? how would you go about doing that? thanks again for all of your help

A 307 is a 283 bore and a 327 stroke. Yes it can be made into a 327. Yes it can be made into a 350. NO, It CANNOT be made into a 355.

A 305 has a very small bore with a 350 stroke. No it CANNOT be made into a 350.

A 283 and a 307 can not be bored safely past 4 inch. That is a stock bore 327 or a stock bore 350
