I do not want to go real fast and get hurt wrecking it, I will just be driving the car around the block every summer weekend so the car will last as long as possible. When me and my dad bough the Impala we thought it was a a 350. My dad is trying to get me to use the 267 because I am on a somewhat limited budjet but, my mom says if I get the new motor and run out of money she might help out because I'm building it for my education.
