Horsepower loves the “other engines”, classic, yet less famous, muscle car engines. They find a junkyard Cadillac 500 big block and use some modern-day performance parts to make a monster out of GM’s biggest luxury car engine. As expected, the final truth is in the dyno numbers.
We continue our build of a Buick sleeper station wagon. Time to get serious with a Pontiac block, precisely machined at Butler Performance, built up with high performance parts plus a turbo charger. It all finishes with a power test on the dyno.

Horsepower’s back to the second annual Holley LS Fest. It's an event where LS-only powered cars compete on the drag strip, the autocross and even a drift car challenge.

Water/methanol injection has been used successfully since World War II as a way to enhance power by increasing octane. Horsepower conduct a pair of first-ever tests – one for naturally-aspirated engines, another for turbo engines. The results may astonish you.
Horsepower embraces the latest supercharging technology from Edelbrock and applies it to a new, Hemi-powered Dodge Challlenger. Plus, a “heads-up” on picking pistons.
The guys install their uniquely designed, newly built LS engine in a ’69 Camaro, along with a race-ready trans. Then it’s put up or shut up, as they pay it off a quarter-mile drag strip. Also go behind the scenes at the home of a top tool box manufacturer.
The LS engine and the first generation Camaro are a match made in high performance heaven. With help from engine specialists, ATK, the Horsepower guys build a carbureted 408 version with hopes for big numbers on the dyno. Plus, a one-of-a-kind race event where Prestolite Gathers late model muscle machines for their MMX Shootout on the strip.
It’s a Horsepower first – the buildup of a classic Buick 350 small block. From the boneyard to the dyno cell, discover how to enhance the factory performance of a little-known Chevy cousin and keep its original looks.
Horsepower visits the inaugural “Run to Music City”. It’s a pro touring event loaded with beautiful old muscle cars, all modified for power and performance on the autocross, the speed-stop challenge and the road course. Plus, we show how to pump the performance of a six-cylinder Mustang GT.
Horsepower helps legendary racer Mario Andretti build a supercharged, modified, stylized Signature Camaro. It’s a one-of-a-kind car with a special mission. It’s destined for the Auction block with all money going to the Wounded Warrior Project.
We use a bunch of re-purposed parts and a whole lot of massaging to build a real world bracket race engine that’s got plenty of competitive, consistent power.

Legendary engine-builder Keith Dorton joins the Horsepower guys in the build of a new Dorton series circle track engine. Keith shares shop secrets from more than 40 years of building championship race engines.
The Horsepower guys forge ahead with their ultimate “sleeper” project. First, they drop in their 610-horsepower 427 into the ’97 T-bird, then, after massive modifications, mate it to a new-tech tranny and complete the exhaust system. Plus, a trip to the Matco tool expo and the testing of a powerful coolant additive.
