Screamin FC

ive got an 86 fc non turbo with a minor bridgeport, s5 rotors. its got the stock 440s in it now, my question is ive got some 550's for it and was wondering if they would be able to go in without any other supporting modifications. i also have a walbro 255 fuel pump and a jacobs rotary power pak that im going to be installing in the near future.and the guy i got the power pak from also has a racing beat fuel injector controller. would this be useful for what im trying to do as well?

non-turbos run rich as hell, putting bigger injectors just make it worse. you would be better off with factory injectors and factory fuel pump
