This was mid process. I replaced the stock cylinder heads and lower intake manifold with the supercharger heads and manifold. I also replaced the harmonic balancer with the supercharger version. I added a different ignition coil bracket, supercharger belt tensioner along with the idler pulley below, the supercharger fuel rail and injectors, and I’ve had to modify the engine bracket on this car to allow the added belt to have enough room and I also modified the throttle body to mount on charger.
