My worst and best 318 powered vehicles, first the the worst was a 1983 Chrysler Cordoba with every available option bought new, that poor 318 was rated at a little over a 100 hp and coupled to a 2.45 8 1/4 rear. Kind of gutless in a 4000 lbs car, but I will admit engine itself ran very smooth. My biggest complaint was when you kicked it into passing gear the car would run up to 85 mph and stop, didn't have enough power to pull that few more rpm's to shift into high gear. You had to let off so it would shift, and then after the shift it wouldn't even hit a 100 mph.
My best running 318 was a 5.2 magnum in a 96 Ram 1500 sport 4x4 with a 5spd manual, 3.55 gears and suregrip, for the 8 years I owned it everybody that road in it or ran with me towing my car and trailer all thought it had a 360(5.9 magnum) in it and were shocked to learn it was a 318. Dam that truck ran good, was a sad day when I turned the keys over to the dealer when I traded it in 2004 for a Durango
