Take a look at this 1959 GMC stepside truck with 4.8L LR4 engine swap. The engine is controlled by a Yates EFI engine harness. The power runs to a 4L60E automatic transmission and then to a 10 bolt diff. The truck rides on a modern suspension and Airlift airbags which lets this truck sit really low when it wants.
