My car has EFI already. Therefore, the fuel system is there already, along with the ECU. There will be some slight modification to the control system, mainly the coil drivers because I have LS coils which are smart coils, while the hemi coils require an external driver. I'll also make a new harness for the hemi. Again, we're not talking big dollars here. I also own the engine. The biggest expense would be mods to the engine, mounts, and headers. Otherwise, there's no way this would be close to $10K. If I would leave the engine stock, the swap would be relatively cheap since I already have most of the big dollar parts.
