hi, i have a 73-240z, and a 77 280-z. both cars are complete. im going to swap engines put the 77 L-28 engine in the 73 240z. i know the swap will bolt right in, but if i go to fuel inj. what all will i need to do? not sure about the fuel pump and lines, and the ignition system. will the all swap over?do i need a crank sensor? and how do i wire the ignition switch. i have the cpu and all the parts. anyone know all the tricks? or know of a web site that has all the info. if so any help would be great
