630-Horsepower Big-Block C10 Swap!

Vintage Chevy C10 pickups are hot, and there are tons of them around the Motor Trend world, including two 1967s that you'll see in this episode along with Freiburger's wild schemes for pickup-truck greatness. It all begins with a grandpa-fresh longbed and a 630-horsepower, 454ci Chevy big-block that has been seen in several installments of our Engine Masters show (its current configuration is the same as that in Engine Masters episode 10, "600hp Camshaft Shootout"). You'll learn how to big-block-swap any '67-'72 Chevy or GMC truck along with a Gearstar Transmissions Stage 4 700R4 overdrive automatic that's beefed to handle the power. But did Freiburger and Dulcich create the ultimate tow rig they were hoping for? Well, let's just say that this truck excels as an epic burnout machine.
