Wont cost me a dollar more to rebuild a WQ block than a WZ so dont see much difference. at the end of the day what makes the HO car and HO? The HO motor and thats still my take. The best advice would be from a person who had an HO car with a non numbers match motor. Not the person with a matching #'s car.
