Odd fire V6 firing angles as you go through 720 degrees of crank revolution firing the 6 cylinders
0 90 240 330 480 570 720

Even fire V8 crank angles as you go through 720 degrees of crank revolution firing the 8 cylinders
0 90 180 270 360 450 540 630 720

As you can see, only the first 2 ignition events of the V6 engine fall at the same crank angles as the V8 engine. Hence, the V8 even firing 90* angle reluctor will not work on this engine. Period. End of story. Well established by the almost 40 years history of the engine.
