In some videos about the 12th march update, appears in the engine a option called modern pushrod, but in the latest video, dissapeared.
What is this system?
Modern pushrods are valvetrains found in for example Corvette engines, so it is advanced pushrod technology. It is not in the latest video because of the year the car is built in: Modern pushrods are not yet available in 1990.
Oh really? That looks like a lie to me and here’s proof:
GM Gen IV V8 (LSX) - 2005 Chevy LS7.lua (38.7 KB)GM Gen IV V8 (LSX) - MOHV - 2005 Chevy LS7.lua (38.8 KB)The LS7 is the highest revving of all the GM LS engines with the biggest bore (therefore the most demanding on it’s valves) and yet even it requires negative quality with Modern OHV to be recreated accurately.

May not be the best idea to call one of the most respected (for VERY good reasons) member of the community a liar in your first ever post on the forums. 
We may have gone a bit too far with their capability to rev, that’s a balance issue if anything. They are supposed to be exactly what Martin says though.

A balancing issue? I think not. MOHV, the way you guys made it, is 100% pointless. Now as much as I’d love to rant about just how pointless MOHV is and how you or whoever is a hypocrite for adding it, that as you say “may not be the best idea” for my third post.
You go from +10 down to -3… look up the price difference on those two engines.
But that’s only the LS7, the most demanding LS engine on it’s valves by a fair margin, if I was comparing just about any of the other LS engines the results would be flipped. The quality sliders are there for a reason and that reason is that some manufacturers have higher quality control standards and as LS7’s are handmade they should have lots of extra quality.
The entire LS family is considered to have MOHC… you are comparing apples and oranges.
Look dude I’m going to be ignoring you after this post because you clearly don’t know what you’re talking about or what I’m saying, but as one last attempt… THE ENTIRE LS FAMILY OF ENGINES CAN BE RECREATED WITH STANDARD OHV, IS BETTER REPRESENTED BY STANDARD OHV AND MOHV IS 100% POINTLESS!!! I bit you farewell.
I, for one, welcome the modern overhead valves. Makes it easier to achieve some level of simple, low-revving efficiency without DAOHC or thinking, “Well, I suppose I could spend half a century in the tycoon part pouring R&D money into OHV so that it’s somewhat competitive with current real OHV engines.” Quality sliders and rich fuel mixtures aren’t my style, these MOHVs are.
Someone needs to switch to decaf. 
See, -3 it a bit too low, but MOHV is not pointless, just kinda overpowered. LS7 does not have +10 quality, it just has a kinda decent, advanced pushrod setup.
What you need to remember is that “handmade” does not have to refer to uber-luxury car interiors level of quality. I can also refer to cheap PSP knockoff hand-made somewhere in a Chinese sweatshop. The LS engines are somewhere in-between, I guess.
I just wanted to ask what strange things are going on with Brucemation, he seems very angry for very weird things. 
Okay I explain it nicely one more time and if you continue to be a total asswanker then you get banned, okay?
Thing is: what you show in your OP is valid criticism, it points to a bit of an imbalance with the game, namely pushrods becoming too good and MOHV being a bit too good without techpool. That needs to be addressed, maybe by stopping normal pushrod’s natural development at a certain point (when MOHV come in). That would be reasonable. We’ll have a look a bit further down the line to see how it works out best gameplay wise.
Cheers!
Maybe stop standard OHV at 1980-85 and move to MOHV. I think that the rest of the world stopped making new engine models with OHV at that time, only 'mericans continued.
The thing is that MOHV meant for sportier and more expensive engines, as it is quite expensive due to it being made from expensive metals.
OHV was still being used in more modest engines well into the 2000’s, in the form of a 2.2L in the Chevy Cavalier.

I want to start off by saying I’m not new, unless if you consider following since late 2013 as still new… Anyway in previous builds of the game I had to lower valve-train quality on the LS1 and I don’t remember any of the others exceeding +3 except for the LS7 and while I’ve only done the LS7 so far in this build, OHV is still similar enough to what it was previously that I can tell I will only need maybe +1 extra valve-train quality than I did in previous game builds. Now that’s out of the way I’ll now address you individually.
Kubboz: You certainly have a good point about handmade stuff, but I do believe I remember reading how engineers from GM’s GT1 racing team were involved in the LS7’s development, at the very least it’s a fact that the C6R’s engine is based on the LS7. Clearly a lot of extra quality went into the LS7 and if you think +10 is too much for the valves, then that’s fine I guess but you can’t deny how uber-luxury car interiors level handmade quality went into it’s pistons. If not then I’d love to see your explanation as to why the game has such problems with the LS7’s pistons which exceed the RPM tolerance of forged.
Killrob: If you really want to go down this path of like swapping MOHV with OHV while making it a bit more durable and making OHV worse or whatever it is you’ve decided you must do despite in the past saying different lifter types etc are represented by the quality sliders then sure it’s your game I guess, but why only the mid 90s onwards? A new pushrod valve-train is desperately needed for the mid 50s onwards to represent the solid lifter style V8s that America’s big three all started making at the time, people have been begging for it to happen for years and now you add one for the 90s onwards only when the OHV option you already had was good at representing the LS engines you claim MOHV is meant to represent? That makes absolutely no sense to me, in fact to me it seems like you did it just to troll or tease fans who wanted a new pushrod option.

But when was the engine DESIGNED? Not manufactured. Rover used an IOE engine from 1948 to 1991. en.wikipedia.org/wiki/IOE_engine That is not a 1990’s engine, it’s a 1940’s engine.
Product development is not about “trolling” or “teasing” fans. It’s about coming up with different ideas and different solutions. Some work better than others - and as the game is still evolving, nothing is permanent (at least in terms of balancing).
I remember reading this article a while ago - you reminded me of it when you started talking solid lifters. Having two separate pushrod options as of the 50s makes sense to me as you pointed out, one hydraulic lifter style (equivalent to the current pushrod option - with relatively early valve float), and one solid lifter style (equivalent to MOHV - with the ability to rev much higher).
For balancing purposes, I’d make solild lifters - louder, less smooth, less reliable, have higher service costs, and maybe more expensive - in exchange for maximum pushrod power (between the 50s-80s). 
Since modern hydraulic lifters are more than capable of revving high (ie. the LS series motors, as you pointed out), solid lifters would eventually become obsolete like mechanical injection - overpriced and underpowered (for the 90s-2020).
That said, I like your idea… not your attitude.
I had a 67 Chevelle with a (1965) 425 horse 396 - dual point mallory ignition, solid lifters and when everything was tweaked just so, that engine was a beast. So, yeah, solid lifters would be a nice option…
