Chevy 305

How many horses do I max out of a Chevy 305, and what mods would I need to do to get the power?

How many horses can I get out of a Chevy 305. And if you know what mods would I need to do to get the most out of 305s. Thank you for your time and help. Thank you, Justin

Mix in the trash. You can spend a lot of time, much money, and get some decent power out of it. And then you can also sell, buy a 350, put 1/3rd the amount of time and money, and have a more powerful engine. The 305 is not bad. But if you want to max anything, it is not the engine to go with.
