So I've had this car for about 2 years now and have constantly wanted more power out of it. I would like to swap the 305 for a GM Good wrench 350(This one). But I'm no expert, and this will be my first project and I need to know some of the issues I will be running into. I was thinking about putting on a edelbrock T.B.I intake. Would I need to put put edelbrock heads and a cam? Or could I use the cylinder heads on the Goodwrench? Also will my drivetrain be able to handle the increase in horsepower? Any Advice would be nice. I'm just trying to get a list of things I will need before I start this project in a couple months. Also would it be easier to go T.B.I or Carb?
