its not going to work with an mechanical system. going to have to get a different trans. i did a older sbc swap on mine but i have a 700r4. i totally took the ecm and what not out. however an electric trans will not work with a carb/dizzy setup. unless you buy your own standalone ecu system to control just the trans. in my opinion if youre going to go through all that trouble just go with a turbo 400/700r4/glide. 60's are junk anyway. if you want to see some of my swap go to @theblueobs on instagram
