1988-91 351 will have the side mount TFI. You’ll need to change the gear if you are going to use a roller cam. The TFI module and ECU circuits change a little over the years, but all TFI distributors work the same.

soesn't matter if you get a manual or auto computer.

Just pick up a Mass Air computer and sensor and you will be good. Don't try the speed density. If the computer sees how much air is going in it will know how much fuel to add. Speed density guesses at how much air is going in by looking at the manifold pressure, engine speed and knowing how big the engine is. Going to a 351 screws with that equasion. Mass air isn't as tricked by that.

Bowsher has it right. Ryan forgot to note that as long as you use a mass air 5.0 setup you should be fine on a mildly built 351.

You will need a 351w TFI distributor though. The 302/5.0 has a 5/16" oil pump shaft and the 351w has a 3/8" oil pump shaft.
