A 318 came in this car when I bought it 4 years ago. It originaly had a 340, but it was swapped for a police 318 out of an 84 Gran Fury by someone. The car ran 7.97 in an 1/8 mile at 8000 feet of elevation. It was 42 degrees that day, so there is more in it. Keep comin back to see any updated results.
