Are pushrods indisputably the worse engine layout of all time?

delet

Yes. Flatheads are easily the worst. I cant think of any redeeming qualities

They have a vintage charm?

I'm probably being baited, but pushrods have a huge packaging and weight advantage with V engines, meaning you can have a much larger displacement while retaining the same physical size, except with more torque, reliability, simplicity and lower cost.

They'll run on cat piss 70 octane gas because of a low cr. Also easy to work on.

>redeeming qualities
there is basically no engine head,oil system is dead simple, cooling system also. There were qualities in the times when they were popular.
>They'll run on cat piss 70 octane gas because of a low cr
low compression ratio is side effect of flathead design, not the clue of it. You can design low compression OHV or OHC engine and it'll run on anything too.

Faggot
Get off my board queer

pushrods are super light and dont require cucked VVT (virgin valve timing) nerdy shit.

CHAD valves maintain lift and duration throughout the whole rev range.

>pushrods
>maintaining lift and duration throughout the whole rev range

top kek, pushrods are more prone to valvelift than any other type of valvetrain

>have to remove a head on a Ford 4.6

best part is the ohc serves no fucking purpose whatsoever, its a truck engine so lol 5.5k redline and it's only 2v so it's only use is to take up engine bay space and drive up costs. fucking fordniggers.

>3 hours to remove a head
Lmao git gud, I had this one torn down to the bare block in 2

>he can't read
typical Ford owner

>require cucked VVT
no engine "requires" VVT. maybe except that quirky fiat's 2-cylinder. It just makes good engine better

for especially retarded i will repeat myself

requires 2 camshafts and VVT to make any real torque!

>that image
>posts small Wanker and OHC engines vs LS the size of some of the smaller Euro states
Small Block pushrods make the most of the space they take up, as proven by a typical 1.8L DOHC from a Miata being the same size as a 6.0L LS

Though for torque, can't beat a 472 Big Block Cadillac.

I thought cooling was trash on flatheads?

Can only compress an engine so far before you have to use literal hydrogen because everything else is too low octane.
In the end, there really is no replacement for displacement.

Cooling may be trash but it's dead simple.

But my pushrod engine is easily as light as the two top ones OP.
>only makes 40hp though

t. virgin

t. gauge infection

try taking a bath you fucking fatso

>bathing in your own filth
reinforces the "Disgusting" lmao

S/o/viet is a Mexican manlet that drives a rusted GMC

>poorfag can't even afford soap
let me guess, you are also circumcised

I am 6'5 and the GMC isn't rusty

pushrods push gods

>6'5
LOL no, you're 5'5 little twerp

Flatheads and T-heads are worse than your typical OHV by leaps and bounds. Hell T-heads are much worse than even fucking flatheads.

>implying not having soap is the problem
>implying you shouldn't constantly cycle the water instead of BATHING IN FILTH
disgusting to be honest

T heads
Why do they even exist. Almost the complexity of DOHC but the characteristics of an old Briggs and Stratton engine

Because they existed even before Flatheads.

They are basically twin cam flatheads. I wonder why they were even designed

Because fuel was shit back then and it could run it with no problems. I don't think they've been used since the 1970's, and that was in a damn lawnmower.

>They are basically twin cam flatheads

Are you thinking of the same engine?

I mean technically the T-head is a flathead engine it's just not the typical L-head

t. butthurt manlet

>I cant think of any redeeming qualities
Really good packaging, A V8 flathead is tiny. Also, piss easy to manufacture. They knew how to make V8's, DOHC and 4 valve engines back in 1912 but making them cheap was impossible, so you resort to dumbing your ideas down into they're cheap.

>low compression ratio is side effect of flathead design
Which you can fix with BOOST

>pushrods are super light and dont require cucked VVT
Explain then why all modern GM and Dodge pushrod engines offer VVT, with the Viper even offering fancy cam-in-cam independent VVT.

>pushrods are more prone to valvelift
I better hope they're prone to lift their valves, they wouldn't work without.

>maybe except that quirky fiat's 2-cylinder.
Multiair isn;t like traditional cam phasing, look it up.
>It just makes good engine better
VVT and VVL are economy tools to make a high-strung engine cheaper and more fuel efficient on the bottom end, not the other way around.

>mass
>irrelevant
Newton would like a word with you.

Pretty sure he meant valve float.

I love how bentlys have the name of the man who built the engine so you know who to blame when something goes wrong

>T heads
>Why do they even exist.
Because they're a good compromise between a DOHC crossflow engine and a sidevalve reverse flow engine. You can get a crossflow engine (which improves airflow) without bothering to do the research on how to make an OHV or even OHC setup.

Also, T-head straight eights are fucking sexy.

>which you can fix with boost
Explains why theyre all supercharged

I've never had valve float on my CX500, even at 10K RPM. 10K RPM with a 3'' stroke (like on a regular 302) should be plenty to destroy your bottom end with a 25+ m/s piston speed.

you are retarded

yeah this

Fuck I replied to him

Sorry guys

>valvefloat isn't real because I can't feel it

It's a problem for old shitty V8s. 305s would do that shit if you tried to push some of them over 5,000 rpm.

Factory redline is 9750RPM, I doubt Honda ever made something that would float the valves anywhere near redline.

t. found valvefloat on an MC22

The problem there isn't that it's a pushrod valvetrain, but it's a smog era valvetrain designed and built by Americans. They can't even make 4v engines.

Even pre smog era shit from the 50's or 60's wouldn't rev out much unless it some hot performance engine.
Old 283s had 3" strokes but you're wasting your time past 6,000 and run the risk of floating valves.

Not really fair to compare a car to a motorcycle anyway.

My bike actually has a low octane / bad fuel mapping lmao

Who dis

The new duke 690 engine is a 1 cyl sohc and makes 74 hp while weighing 40 kg
