Vintage Chevy C10 pickups are hot, and there are tons of them around the Motor Trend world, including two 1967s that youโll see in this episode along with Freiburgerโs 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, โ600hp Camshaft Shootoutโ). Youโll learn how to big-block-swap any โ67-โ72 Chevy or GMC truck along with a Gearstar Transmissions Stage 4 700R4 overdrive automatic thatโs beefed to handle the power. But did Freiburger and Dulcich create the ultimate tow rig they were hoping for? Well, letโs just say that this truck excels as an epic burnout machine.
