So I'm looking to bore and stroke my 318 to a 390; are there any ways around the computer aside from a carbureted setup (I like my 4-speed)? I don't know of anyone that does custom tunes on the '92-'93 Magnum motors. Has anyone tried the any of the Mopar Performance PCMs? I doubt they're built to handle 350-450 horse/torque. Any advice would be appreciated.
