imo, the "durability" you mention just came from the old-way of designing things. The good ol days of overengineering. If thats true, a new pushrod v8 may be just as unreliable as a new OHC design. Just thoughts. From a fundamental standpoint, ohc is superior in every way. I bet if you were able to design a badass version of each, the increased system mass of pushrods would limit high end rpm and increase wear at all mating faces. Interesting to see what they come up with
This engine is not designed for high rpm use, its designed to be a low end torque workhorse.
Its going in a 3/4 ton truck, not a race car.
But you're right, overhead cam engines do have an advantage in high rpm applications but I'm sure you probably know torque output decreases with rpm after its reached its peak.
why stop there, why even have cams at all?
Its possible to build a camless engine with technology that exist right now.
You can highly overcomplicate things or you can build something simple that you know is reliable and works for its intended application.
Simple, reliable, strong, thats what they are after here and i bet they will sell the fuck out of them.
And you're right about reliability I guess in a way because they could for sure build an unreliable piece of junk.
But I doubt that's what they are going to do in this situation.
