I happen to prefer diesels, more bottom end torque, as much horspower when tuned properly. They turn out good enough fuel mileage enough to make up the cost of fuel in the first place, not that I have to worry about that as diesel is 20 cents a litre cheaper here anyways....If I could find a 4bta cummins around here with low hrs, or cheap enough I could rebuild, I'd do the diesel swap in a heartbeat.
