Pure Magnum swap

Now i'm dealing with intermittent spark, most likely the Crank Position Sensor, I sheared off the original while mating the trans. $50 lesson learned, put a pair of vice grips gently on the sensor (after cutting a notch in trans bell housing for it) and it kept it from cutting wires. I replaced the coil, distributor cap, and plugs.

LOL, I can laugh at that because I broke mine when I put the engine in...I also had intermittent spark because the sensor was broken off the mounting tabs... doh!!

Does it start then die, or sputter when running? If it's a PCM with security it'll start for about 5 times and die, then wont start ever.
