OHC vs OHV fewer moving parts
I have seen a couple people on this forum claim that an OHV engine has fewer parts than an OHC engine, but to my knowledge it is the opposite. An OHC engine does not have valve lifters, pushrods, and in some cases rocker arms. If they are referring to a 32v DOHC such as the 5.0 coyote they may have a point due to the extra valves, cams, and rocker arms.

OHV does have more parts, and to my knowledge that's mostly why it limits how high a pushrod engine can rev.
Hence why people salivated over the fact that GM got the LS7 to pull to 7K Push rods push Gods |

One of the reasons that I traded my 13 5.0 for my 12 SS is the simplicity of the LS engine. The 5.0 is a screamer of an engine, but very complicated. became out of warranty,so if it broke I was walking. The 5.0's have 4 cams 4 timing chains, cam phasers on each cam. 32rocker arms 32lash adjusters. They do have more parts than an LS motor.

Different strokes for different folks. They both make great power when done right.

Both OHV and OHC have been around a long time. It's not so much which set up is being used that creates a problem as it is the RPM levels any engine is built to reach. RPMs kill engines. Longevity and reliability drop off quick as you spin the engine faster and that applies to both OHV and OHC. IMO, what is the use of being able to spin the valve train at 10k if the rods blow out the bottom end.
Rather than spin the hell out a smaller engine, I prefer to increase displacement or add boost. Increased displacement and boost would be the ultimate solution, maybe throw in some nitrous and/or alcohol. Quote:
And all that electronic chit did fail. Fuel injection was on Vettes in the 50s. It took until the 21st century to get it right.

Personally, I don't see it as a debate. I know how to build a car and know what I like and why I like it. I do find it humorous that people come on a Camaro site espousing the virtues of one of the features of the current Ford motor and get all butt hurt when others disagree and have valid reasons for their disagreement.
