This is one of the best old Ford trucks as far as we are concerned, but they can be hard to come by. Restored versions tend to be pricey but it’s a great choice if you can get ahold of one.
Another party trick of the 488 is its ability to run on compressed natural gas (CNG) or liquefied petroleum (LPG) in addition to regular pump gasoline. That’s thanks to the stainless valves and hardened valve seats. A forged crank, rods, pistons, full-length cooling jackets, and cast-iron head and block ensure maximum durability and longevity even in high-stress situations. Just add your choice of intake manifold, carb, and all the regular bolt-ons we talked about earlier, and you’re good to go.
This has been but a taste of the vast GM Performance Catalog. GM crate engines run the gamut from affordable and economical four-cylinder mills to gallon-per-mile big blocks that sound like the devil gargling Listerine. And the future is bright: Chevrolet is bringing back the COPO Camaro and the newly-launched 2019 ZR1 packs 755 horsepower and a 210-mph top speed.
The name “Highboy” was not an official Ford term but a nickname given to it by enthusiasts. The 1977.5 models featured a negative arch leaf spring, which dropped the height by 4 inches leading to the “Highboy” nickname for the pre 1977.5 models and the post 1977.5 models being called “Lowboys”.
