Gen lll hemi install in a 67 barracuda

Another question i have do you need the computer that came with this motor? Or does the hotwire set up take care of that? I followed the step by step from Mopar Action they did on a 69 dart but they used a 73-spool type Kframe and, i would like to stay with my biscuit type kframe that i currently have. I noticed that schumacher sells that type of engine mounts but are currently out of stock and won't be available until April. like i said just starting to do my research and parts gathering
Thanks
Pat
