Why the /6

I have had V8s. They're okay, but they don't run smooth, they don't even idle smooth. you have two cylinders fire next to each other in the firing order. That doesn't happen with a Slanty. 1,5,3,6,2,4, nice and smooth. A V12, V10, Five Cylinder, four cylinder, all nice and even. Not a V8, unless you buy a Chevy and put a very expensive 180 degree Crank Shaft in it, but then you have two four cylinders on a common Crank.
