The question was why was it called an "even fire", the reason is because the previous one was called an "odd fire". The reason being it was a V8 with two cyl cut off leaving a three throw crank and a distributor with an odd spaced cam. It was an "odd fire" being it skipped two cyl as the distributor rotated making a not so smooth running motor. Below is a diagram of the distributor cap showing the even fire V6, Odd fire V6 and V8.

On the V6 being an aluminium 215 with two cyl cut off, I am sorry, it was of that design, just as the 300 Buick motor was basically the same, they used the same water pumps and valve train for instance so I guess it was more the 300 with two cyl cut off. They did have a 340 same basic design I think with only the bore being different than the 300 so maybe the six was basically the 300 but with slightly larger bore?
