Like the old COPOs of the 60s, the 2011-14 models adhered to strict NHRA guidelines. That meant super-small production numbers and a price payable only by professional race teams. It also meant the car’s engine could only make 530 horsepower. But much like the Japanese engine restrictions of the 1990s, that figure seems to have been framed in air quotes. In 2016 a (not extensively) modified 2014 COPO Camaro ran an 8.323-second quarter mile at 165.80 miles per hour. Doing the math, that car was making closer to 1200 horsepower. 1200.
Enter the LT4 crate engine. Power comes on fast: a 1.7-liter Eaton supercharger spins at 20,000 rpm to force 9 pounds of boost into this 6.2-liter engine. That results in the same 650 horsepower and 650 torques you’ll find in the Z06 that’s sitting over at your local dealership, but for a fraction of the price.
They mechanically lock the rubber to the rim so that sidewall sag from less than stock psi doesn’t drop the bead and leave you stranded. An added bonus to these is that their distinctive look adds to the curb appeal along with other Jeep mods.
The Chevy El Camino is probably the best-known example in this category but the Ranchero was the first and is a pretty cool car/truck. The Ranchero was introduced in 1957 and was in production until 1979. A total of 508,355 units were produced and while we like the early models, they are all pretty sweet.
