Overall I think it depends on which Motorsport you are doing which determines which engine is the best. If you are like me and you drag race OHV are overall better because they make torque easier and cheaper, they seem better for Off Road and Monster trucks too. As where OHC motors can reach higher RPMS they fit road racing and Rally better, where racint at higher RPMS for a long period of time is common.
@NicksCorvetteMan Strong lightweight parts and a lot of money into a dated technology. I don't really know, but the better question is why is the OHV config still used.
Thanks for the awesome vid :) My 2001 Ford focus had a SOHC engine (a piston broke) and I want to exchange it with a DOHC. Is this a good idea? I read alot of complaints about the ford focus 2001 SOHC engines so I'm trying to avoid the same type.
@ThunderViktor As long as you find something that fits, I see no problem. I actually had a friend with a 2000 Focus who also had to replace the engine. I'm not sure what engine you plan on replacing it with, but DOHC is the modern valvetrain style.
@LongRangeBullet Yes, exactly. This is where the valves do not entirely close during the rest of the engine cycle other than the cycle they are needed for.
Not only will the OHV engine be lighter, but it will have a lower center of gravity compared to SOHC and DOHC. While this may not be important from an engine perspective, from an overall handling perspective it helps tremendously.
@EngineeringExplained True, but DOHC boxer engines consume a lot of space in an engine bay and often times interfere with suspension layouts and aren't what one would call "compact"

How can NASCAR race-car engines can turn 10000RPM and still maintain a OHV configuration?

A fellow engineer. Nice. You should do a video on short barreled rifles versus long barrel, assuming you're not allowed to change cartridge pressure.

Wow buddy, you have such excellent video's they are so well explained and simple to understand for anyone. Great Job man!

So, that problem at high RPM's you were talking about with the pushrod, would that be valve float, or is valve float something different entirely

@joeslimon True, but this depends on the layout as well. A dohc boxer engine will have a lower center of gravity than a "V" pushrod engine.
