Yep Indy folks thought they were just allowing folks to take a production engine with a single cam, which was allowed to have a larger 209 cid and a higher boost, to be more competitive with the typical DOHC engines. They eliminated the prior need for it to be a production block! Rodger had an idea resulting in what was called "The Beast" that dominated Indy and ultimately had to be ruled out! The relative heavy cam follower used cams to rotate it to lift and another lobe to close! Similar to "no valve springs" desmodromic cam operated valves as was used, for example, in a Ducati motorcycle!

If a new car comes out and the manufacturer says it has an OHV engine, it’s not suggested that simply means it’s not a flathead. That just makes you sound out of date.

1. It sits low because it’s an OHV. That is not true, a OHV engine probably has a higher CG because the heads are taller and have a lot more parts in them.
2 OHV means the cam is in the block no the heads. that is not true either it means the valves are in the heads not the block.
Technically a OHC engine is also a OHV engine.
I find these attempts to educate through text messages very tiring. Some people will never fully understand the workings of a internal combustion engine. So class is over, have a good day.

Your previous statements tell me that you don’t fully understand:
1. It sits low because it’s an OHV. That is not true, a OHV engine probably has a higher CG because the heads are taller and have a lot more parts in them.
2 OHV means the cam is in the block no the heads. that is not true either it means the valves are in the heads not the block.
Technically a OHC engine is also a OHV engine.

It’s obvious it’s not a flat head engine, so it’s either a OHV or a OHC. Yes both of the have valves on top the head instead of in the block. Today they mean where the cam is located. Why people today use the term OHV to mean the opposite of a OHC I don’t know, they just do. I guess “underhead cam” just didn’t have a good ring to it.
Thanks for the trivia, but it’s still irrelevant to this particular topic.

I realize the new LT2 engine was introduced in the new 2020 C8. Is this engine being used in any other GM models? The reason I ask I just watched Jay Leno’s garage review and test drive of the 2023 Z06, he mentioned to the GM engineer that this Z06 was special because the all New LT6 will only be used in the C8 Z06 exclusively like no other Corvette and the engineer did not correct him. The engineer did mention Originally the C6 Z06 came out with the LS7 exclusively until they used it in the CAMARO Z28 and the 427 Corvette in 2013.
I would appreciate your thoughts and knowledge on this subject.

But alas, i also saw where Jay drove the Tesla Plaid S($129,000) that broke the Chiron's(3million $)1/4 mile record. IMO the new exclusive C8/Z06 is a noble achievement but arrived at the end of the ICE era.

monster truck tires and wheels help lower the CG. And OHV motor won’t hurt. Nobody ever says,” I wish my vehicle was more top heavy, “

Similar, as they’re all part of the Gen V architecture. https://www.holley.com/blog/post/eve...n_v_lt_engine/

Now, b) pick a number as to how low a CoG has to be in order to be considered a Low CoG ?? _____________________
{Remember this number has to be lower than the roof line of the current C8.}
Now compare a to b ??
And answer the question:: is a lower than b ?

So, smarty pants, a) if the vehicle has 55" of ground clearance how low can the CoG actually be ?? ___________________

Thats why front end lift immediately drops you back to hugging the ground when you’re done with it.
