In the real world, hp/l really doesn't mean much, especially when comparing two different architectures. The Coyote makes more hp/l than the LT1, yet the 5.0 is slower than the SS by a good amount. The previous gen SS got similar mileage to the 5.0 despite making less hp/l and being in a heavier car. I mean, I could find some small displacement 4 bangers making way more hp/l than the Coyote. Does that mean the Coyote is garbage?

DOHC engines should make more hp/l as a function of their design. Handicapping the LSx at 5.3 liters makes no sense because it is negating the biggest benefit of the OHV arrangement. If you are stuck with displacement caps, like racing or government regulations, then DOHC makes more sense because it will always make more power for the same displacement. If the only concerns are weight and packaging, then I believe OHV is the better choice. For the same power, it will be generally smaller and lighter while making more torque than a similar DOHC engine.

Again, the Engine Masters capped displacement. There is no way a OHV engine can compete at the same displacement. Why limit the LSx to 400 cu in when there are factory LSx in the 427 range and aftermarket blocks in the 500+ cu in range? That's going to put the LSx at a big disadvantage. If they had done the same challenge but limited rpm to 7000, then the Ford guys would lose their minds because DOHC is better for spinning at high rpm.

LSx is cheap because it's in many vehicles. The Coyote is expensive because it's not. That's the way things go. That doesn't make one better than the other.

I know you can't literally remove half the valves and three of the cams and end up with a functioning engine. I was trying to prove a point. If you can't understand that, then I can't help you.

The only one ass hurt is you because you want to limit the LSx to make it "fair" when it wouldn't be.

The Coyote is the most complex and badass engine built in the USA today. GM had a good design when the hooked up with Mercrusier on the Northstar but they did not pursue it due to the cost. We all lost out on that decision.
