Yes and no! 75 is a horrible year of Chevy struggling with emissions. the heads aren't good, so replacing them will boost power, especially if you look to Vortecs. The "no" is that it costs as much or more to build a 305 as it does a 350, and the 350 brings a lot more torque to the game. So why not start with a 350?
