"I have put a 429 motor into my 63 Fairlane. Then I got the bright idea of adding an EFI set up from a 90 truck 7.5L on it. The result is that it does run very well and it is a nice addition to my little car HOWEVER, \nsince it came from a F-250 truck, the computer THINKS that it is still in a truck and runs like it. A friend of mine  suggested putting in a computer and mass air sensor from a 94 mustang to bolster the preformance. He says that that year mustang came with 24 lb injectors like I'm using now (since the computers are set for the injectosrs that they are using) and the mass air I can add and the harness I can make... any Ideas. \n\nHow can you tell what size  of injectors are being used. Where can I find a wire diagram for that year or mustang?"
