DOHC vs pushrod. Chevy is taking the pushrod engine to the extreme. The benefits are low cg, lower weight, much more compact engine. With the displacement that big, it makes great torque below the curve in NA form. Compare that with many smaller displacement DOHC engines that produce far less torque. Good example was the M3 V8, less than 300. There are some ways to get the torque up other than super/turbo charging, but they generally include revving very high and more exotic materials and more failure points, not to mention still relatively low torque at low rpm. DOHC tends to be capable of more hp and torque, but giant DOHC engines take up too much space and FI can really take it to the next level. Pushrod is kind of Chevrolet’s specialty and they kind of defy the logic of what should be outdated, but the benefits of packaging and simplicity are hard to deny (like LS3, LT1). I have the LT1 in an SS 1LE and it’s a great torque monster. Nothing NA really compares (except a few more exotic things like LS7) and it does better NA than many turbo cars with lots of torque. Massive torque from displacement at low rpm. There comes a point though if you want more that you have to go FI. The amount of area under the curve with some of these turbo 600+tq cars these days is insane. Off the line and especially with AWD, they will win the straight line all the time.
