As some of you may know I have a 70 C/10 with a mild 350 smallblock. I love driving it every day to school, but I want a little more power. I found a kit from Summit that has aluminum heads, intake, cam, and etc. that is supposed to give a 350 410hp for about $1500

I have also considered getting my 350 rebuilt, but I don't know if that would be the best way to go. What would you guys do?
