How much of a difference would there be in times between a reg. cab and a supercab? I have all the same specs as 54regcab just s/c.

BTW anyone have any suggestions on how to break in a new 5.4? I got my truck Aug 20th, about 2 weeks ago, and I have about 280 miles on it. Most of my driving is short city trips. To and from school(about 1/4 of a mile), to and from friends(1/4-1 mile), to and from football(1/4 mile), but I do freeway driving to the beach or other cities. I just filled my tank last Saturday and on my first tank of gas I was getting about 9.2 mpg, which is real bad.

Anyone have any ideas on how to break in engines well?

The s/c is about 200# heavier, so it'll be about 0.2 slower in the 1/4.
