The engine cage bolts to the cab cage via bulkheads at the firewall. Trim panels add a finished look and keep debris contained in the wheelwells. The Spare Parts Truck is propelled by a big-block Ford 460 that’s been treated to a mild internal build. Custom Autofab headers fit the truck perfectly and maximize engine performance. A heavy-duty C-6 automatic transmission with a manual valvebody backs up the 460, completing the powertrain package.
