You will love the big block in the Nova ! I have a 72 Mark 4 in my Nova . When I fire it up you can feel the power it is awesome . I have heavy duty springs in mine and I actually would like to cut them a little. It also seems a lot liighter in the rear. I plan on moving a little weight around . Battery in the trunk , fiberglass hood and maybe Aluminum heads someday . They are heavy around 750 lbs but I think it is well worth it. Welcome aboard the Big Block Nova club!
