>>28921711>2026 and it's not dohc Wtf is this boomer ass shit
>>28921719Ill take pushrods any day over this shit
>>28921721That's literally based, doh timing chains have been giving hundreds of thousands of miles if yoy just take care of it and they can vary the cam for the most juice at whatever rpm

>>28921719The advantage of ohv is the ability to angle the valves vertically straight allowing for the larger valve area than once and dohc. This provides ohv greater air flow at the cost of lower max rpm.
>>28921774>once and dohcohv and dohc*
>>28921711Technically 6.66L and yes
>>28921711>on purposeWhat does the number 6.7 represent to you?
The kids like 6.7, it's 6.66 rounded up
>>28921774this isnt correct>The advantage of ohv is the ability to angle the valves vertically straightthis is actually a reason ohv is bad, because you can't angle the valves any other way which means you have less valves, meaning you need larger valves to make the same airflow which are heavier and consequently lower the maximum rpm. ohc engines can angle the valves to optimize space, meaning they can have more valves and thus superior airflow and higher rpm
>>28921781And even thats not right you can still cant valves with OHV, but its a hack job with twisted rockers
>>28921721>>28921746>>28921748>>28921754>DOHC is bigg -ACK!Wrong.
>>28921781God damn I hate fucking zoomers that pull random bullshit out of their ass.Do you even know what a HEMI engine is?
>>28921711god it looks so chunky
>>28921799Its big when its not some backyard home made jerry rig
>>28921746
>>28921822Head bolts through the intake ports is brown-tier.
>>28921746Both look qay too unnecessarily complicated
>>28921799posts some irrelevant one off gimmick prototypecool, but lets stick to actual production engines that were produced in meaningful wuantities
>>28921854Increases HP by providing a more complete atomization of A/F mixture through turbulence.Actually been tested and verified.
>>28921854Sort of undermines the claim that ohv valves can be angled.
>>28921892you can't expect an incel to understand that.
>>28921721Agreed. No plastic guide bullshit, no stretched chains, and only one cam to swap.
>>28921892How does a stud that terminates under the intake port increase turbulance?
>>28921725Takes less effort, less parts, less time and no tensioners or guides on a pushrod engine. You can even swap heads without touching your timing.
>>28921934There is a guide right in the middle of that image, r-tard.
>>28921938Thats not a guide retard, its a damper. Its purpose is to reduce wear/noise/vibrations and prevent chain whip which can wear the chain out sooner. Its not even neccesary for the system to operate, whereas in a OHC engine a failed guide is a guaranteed engine failure. Most gm engines outside of the corvette/V cadillacs dont even have one.
>>28921754Chevy v8s are so much easier to work on than dogshit modulars it's laughable. Imagine an engine bay, with room to work! Crazy thought
>>28921938its not a guide. you can remove that piece and the engine will run just fine. try removing a guide on a ohc engine and see what happens.
>>28921781Wrong the limits of rpm from an ohv design comes from the higher valve train mass. Ohc and dohc reduces the amount of valve train mass increasing the limit of rpm but comes with the cost of higher rotational mass
>>28921960No, because a chain guide is a critical component in a timing system and without a guide in place to keep tension the system fails instantly. Timing chain guides double as tensioners. Pushrods dont need tensioners because the cam and crank sprockets plus chain length mechanically restrain the chain already. Thats a damper and its main function is to reduce wear. Even in high rpm applications, the risk of jumping timing comes not from lacking a tensioner, but from premature chain wear from excessive movement which the damper is meant to reduce. There is nothing critical about a damper in the functioning of a pushrod system. All it does is reduce wear. Oh, good job deleting your post. Maybe you realized it was stupid.
>>28921968>a chain guide is a critical component in a timing system and without a guide in place to keep tension the system fails instantly.Lol, lmao evenT. Škoda
>>28921968I should add to this.In very high performance applications like Nascar engines that run wot at 8500+ for an hour straight, you'll often find belt systems with a single roller tensioner. Thats still continents away from the level of complexity of even a basic ohc system.
>>28921774>ohv>vsBoth single and dual over head cam engines are also over head valve engines. Shitroders just have an inferiority complex and needed an acronym too so they chose OHV since they are stupid and dont know how engines work.
>>28921991Or you could just not be pedantic and autistic and understand the distinction like everyone else
>>28921754Left is cooler.
>>28921991When overhead valve engines came into existence in mass production cars, ohc was still a long ways away from large scale adoption. It was in fact overheadcamlets that had to create their own special snowflake acronym because ohv was already taken.
>>28922008J.W. Raymond patented an OHC engine in 1892; the Springfield Gas Engine Co. produced an engine in 1895. Early Production/Racing: The 1902 Maudslay (designed by Alexander Craig) and 1903 Marr Auto Car.
>>28921711yes(6.7, vee 8)
>>28922014Mauslay stopped producing passenger cars after ww1. Marr stopped production of the auto car after selling about 500 cars, and it was also one of the most expensive cars in its market at the time. It took almost 70 years for OHC engines to make it into a mass produced passenger car.
>>28921836>>28921860>b-b-b-but the heads would be WAAAAY bigger on a production engine OH NO NO NOPUSHROD BROS DID WE JUMP THE GUN?
>>28921822>>28921917As a result of the hemispherical combustion chamber and canted valves, those heads are no smaller than OHC heads.
>>28921934>has to remove BOTH heads just to pull the cam or lifterslmao
>>28922155wrong
>>28922158Don't tell me you're going to disown the LS engine now?It's the crown jewel of pushfaggotry!
>>28922155this is simply untrue for the LS or gen III hemi.
>>28922170post vid of you swapping lifters on your LS without pulling the headsthe internet would be very interested in such a feat
>>28921711No it's just a common 409 cubic inch engine. Super common with LSI believe that's a 4.065 bore and a 3.9 inch stroke.
>>28922178Not a problem a ford small blocks. Just a quirk of how GM decided to build their engines. Theres nothing inherent to OHV that requires the lifters to be captive. Beyond that, if you have direct acting cam lobes in OHC, you're still pulling the cams and retiming the engine to access the lifters which is STILL more work than pulling heads on a pushrod engine.
>>28922189lmao no removing the cam cover and timing belt is far less work than removing heads, unless you're some sort of retard who thinks timing cams is some difficult task
>>28922191Did you forget the other 80% of the job?
>>28922196What, removing the cam caps? Lmao
>>28922199So you just stop there?
>>28922162i don't know about the LS but i can swap a cam and lifters without touching the heads on my SBC pushrod engine just fine.
>>28922202Yes once you've removed the cams you've removed the cams, what are you trying to do lmao
>>28922208So you just like talking shit apart and leaving it there? No wonder you like ohc
>>28922210What you want me to write out "then put it all back together"?
>>28922178do they not have wood dowels in your country?
>>28921711>Tunnel ram intake manifold Boomer yeah yeah born in the USA, Oh ya boomer yeah
>>28922220>posting AI nonsense That's the lengths you have to go through to swap a cam WITHOUT changing the lifters you absolute retard
>>28922229Inserting a dowel rod is a great length for you?
>>28922216You seem to think captive lifters in a particular engine series make an OHV engine more difficult to work on than OHC engine, so I really have no idea the depth of retardation you're working with
>>28922237Yeah fishing all your lifters up just so you can munch them with your new cam on old bedded in lifters is pretty retarded.>>28922238>brags that you don't have to touch timing to remove the heads>SEETHES when confronted with removing the heads just to get to the lifters and cam
>>28922242So you just suddenly become retarded when confronted with a different engine configuration? In a DOHC v engine you to remove 4 sets of cam caps (which takes more bolts than pulling a head) and if you want to do the job without acting like a nigger you're going to replace the tensioners and guides as well.Even if you skip the timing components, its STILL more work than yanking heads off a pushrod block to change a cam in the minority of cases where thats even neccesary.
>>28922249Just cleaning gasket material is already more work than removing all the cam caps
>>28922250Scotchbrite and a can of brake clean?
>>28922251A ratchet and socket?
>>28922256So you dont even clean your parts before you put them back in? Man you really are a nigger
>>28922261>NooOoOooO OHC engines are harder to work on because YOU HAVE TO CLEAN ALL YOUR CAM CAPS!!!!!!!
>>28921711It’s 409ci and that is based.
>>28922267I know being retarded for engagement can be fun, but you're trying to argue an engine design with 30% less parts is somehow harder to work on because of literally one part that takes the same amount of bolts to access. Every single other job for an OHC engine takes more work once you get below the valve covers.
>Chains
>>28922277>the same amount of bolts to accessDid you forget about all the shit you have to take off the heads lmao
>>28922284>maximum RPM of 4800>takes 37 seconds to reach thatAt least it doesn't need a flywheel?
>>28922290most mechanically knowledgeable pushrod enthusiast
>>28922288It takes less bolts than getting your cams out
>>28922305did little baby forget about the manifolds?
>>28922309You leave those on the head retard, but I forgot you never worked on an engine before
>>28922310post video of you removing LS heads with the manifolds attached
>>28922288you are latching onto the one thing it might be slightly easier to do on a dohc engine compared to one of many pushrod engines, while ignoring the 500 other things that are way easier to do on any pushrod engine. i own several of both btw.
>>28922320and yet you pushtards can't even admit that one thing
>>28922313Ever heard of a ford small block? Vulcan v6? Both are pushrod and dont require head removal to access lifters btw>>28922320Worse than that, fixating on a specific quirk on gen III and onward GM small blocks as if thats inherent to pushrod engines
>>28922325Because thats not a pushrod quirk you fucking retard, its a GM quirk on SOME of their engines.
>>28922326So you were just being retarded when you suggested removing the heads with the manifolds attached?
>>28922333>it's just a quirk of the #1 most popular push rod engine that we're always bragging about
>>28922334No, because I can do that on my engine. Ive never needed to though. >>28922335And?
>>28922152>narrow valve anglemight as well be SOHC
>>28921991>needed an acronym too so they chose OHV20 bucks says this guy has never seen a schematic of a flat head.
>>28922337Can you do it on a push rod v8?
>>28922351>he's still trying to use wide valve for performanceIt's not 1980 anymore grandpa, a narrow intake valve angle with a straight vertical port flows better.
>>28922539Like this?
>>28922594like this
>>28921719sohc a dick, lol!
>>28922290Add 9000rpm to that and it's accurate for the redlineIt'll also take you to 180mph in less than half that time
