Fuel-injection mania swept the F-Series in 1988; as of this year, carburetors were discontinued for this line entirely.  The 1988 Ford F-150 came off the line with fuel-injected 5.0 liter Windsor V-8 engines, 4.9 liter straight-six with fuel injection, and the whopping International Harvester 7.3 liter diesel V8.

The 88 Ford F150 was the first to ship with a five-speed manual transmission, which improved the pickup's off-road versatility.  Automatic transmission also came as a standard choice.

Trim lines for the 1988 Ford F150 were the XL, XLT, and XLT Lariat.  Extended-cab supercab and 2-door cab setups, as well as short-bed and long-bed models, added to the variety offered to buyers of the 88 Ford F-150.  The solid durability and reliability of this workhouse truck made it a great choice for farm and ranch; its rugged 4-wheel drive lent it popularity with off-roaders.  Tuners especially love the solidity of this classic muscle truck.

You'll have to trade off fuel efficiency for size and power with the 1988 F-150, though; best-case scenario for mileage would be 18 highway, 14 city.
