Inliners International Forums General Discussion Engines tossing around the idea of efi for my 235

thanks

Does the calpak have to come from the same model ecm (1227747). The 2.8l's from 88-92 had a different model # ecm (1228062) wiring is the same though.

looking at the ecm list, maybe I should also look for a 3.1L not sure what truck that came in.
