Can you guys maybe list ideas and ways to add hp, what i will get the most hp out of doing and what it would require to do it (parts wise) and by the way i have a 97 blazer and an engin swap is not an option lol

 

Have a look around this section. You should find a lot of information. Some search terms that may turn up more threads would be "CAI", "headers", "cam", "tune", etc.
