Should I make the swap to G3?

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.
If you want I think I still have my Holley list that I put together for all the Holley numbers. I can send it to you. Be careful on the drivers as I want to say there is two versions for your motor depending on your connectors. Spend some extra time on research and hit the Holley forums. I learned a lot from them. Here is a pix of my POS modern Hemi 6.1 in my Mopar muscle car 72 Demon. I would and will do it again in a heartbeat.
