Just a quick question. Has Ford ever put a 5 cylinder engine in the F150 pickup? My niece's husband stopped by the other day on their way back home. They had just bought an Airstream down in Lake Worth, FL. I was asking him how the truck did and he told me that it did great, even though it was only a 5 CYL. I was a bit taken aback by that remark, but really didn't question him further on it. A little research on Google told me that Ford did indeed make the "Puma" 5 cyl, but only said that it was used in a delivery van, the Ranger pickup, and maybe one other vehicle. This pickup that he was driving was a large F150, double cab affair and definitely NOT a Ranger. So is this combination even possible? And which type of fuel would it be using, gas or diesel. I have no doubt that it was fuel injected (according to Google) but would it be a turbo as well? (prob.) Also, what year vehicle would it possibly be? This truck didn't look brand new, but fairly so.
