Here we go....lol
Thats an opinion. There's nothing wrong with pushrods at all. Dohc has in perks but the pushrod design has proven to work over the years. I can't believe I'm saying this but look at nascar. For a v motor to make that power and spin at that rpm for that period of time is flat out amazing....and before you jump the gun, we all know these motors are money and have been balanced and so on to make this possible.
I'm speaking in general. The fact that they might make cams and other parts is great. Now what if someone wants the choice of different specs from an off the shelf part? Of course you can always do custom parts but that's r&d and down time. That's all I was saying.
