The Detroit Muscle guys slam over a 1,000 horsepower into a huge mid-70’s Mercury with a sadistic streak. The build continues with ignition, exhaust upgrade and fuel system to handle all that horsepower. Then it's time to add an indestructible 9-inch and air suspension to our sleeper. When the build is complete, Marc and Tommy show off the added power to Big Smo @SMOMOTIONTV
