When Doc had the car redone by a very well known chassis builder, I cautioned him to NOT let the guy move the motor back. A Monte Carlo already has a long wheelbase and good motor position. It needed to be built like a pro nitrous car, meaning about 54% nose weight. He(builder) did as he wanted because he had "street car" in his head and the car is 50/50. It's been a constant struggle to keep it from hammering the tire and shaking. On another racers advice, albeit one with a totally different combo, Doc tried a different tire that was actually a MORE aggressive tire. That didn't go well........LOL!!!! We really need to move the motor forward, but that's MAJOR surgery. Plus it really won't hold the tire we NEED because Doc didn't want to bubble the 1/4 panels. So would have to raise the car to fit them, which isn't good either
