ericou812: would be better without the music and have a dude explain how the engine works
matthebest018: Reajust the rockers if it comes loose again you will need new push rods and maybe a cam
oliver morales loza: muy buen video
Mistah Taylah: theres a lil bit more he didnt show. put a engine together with no seals and its not gonna be good
Masmotors: what software is this nice i want it to use
Dustin Young: LOOKING FOR HELP.... bought a 85 c-10 with a done up 350 with aluminum heads, and a nice set of rocker arms and cam, i have had the truck for about a year and just recently started having trouble with some engine knock. i've taken the valve covers off and found a very loose push rod and rocker are on #4 cylinder, im almost ready to pull the heads off and have a closer look any suggestions??????? anyhting wil help ive been told i might have to do a whole cam and timing set
NoFaithNoPain: How dimensionally accurate is this? I am surprised you could get the original drawings!
SanDiegoHotRod: I finally bought the Virtual engine dyno but cheaped out and did not get the 3D Engine Builder version. Helps designing small blocks for sure. Seeing the tuned port gave me flashbacks to when I worked at Chevrolet in 1989. I build custom engines now at my own shop (Corvettes and Customs) in San Diego.
Looks great but I would have used a bigger Harmonic Balancer. LOL
cncdude1: @justforever96 If you were not serious about that then pardon me. I wasn't trying to be an arse. I have had more than my share of prepubescent teens wanting to put "Noss"on their pos ricer. True,topfuel does use 2 valve motors because the rules only allow it. Running rocket fuel kinda helps the HP numbers too. But if you have a too radical cam your springs suffer for it. I build turbo motors which prefer smaller cams.
justforever96: @cncdude1 I take it that you're insinuating that I'm a pimple-faced teenager or something? Wrong. Second, you obviously have no sense if tongue-in-cheek humor, although what I said about nitro Top Fuel engines still being 2-valves is perfectly true. Of course a 4-valve engine is "better" from a performance standpoint, but I like the idea of using a 2-valve just be different. And there is always the Chevy LS and the new Hemi, neither of which suffers much from being a 2-valve, pushrod engine.
cncdude1: @justforever96 First, Go put on some clearasil and ask your mom for your nuts back. Dude you obviously have never taken the valve cover off a motor. It comes down to simple math. 2 small valves have a larger opening at the same height as a single large one. If you try to put a huge cam in a 2 valve motor to keep up with a 4 valve with an aggressive one, your rockers, springs and pushrods will pay the price. It will lope so bad that it will be nearly impossible to drive on the street.
Andy vecchi: To bad engines don't put themselves together like that.
RedResurrections: eww tuned port
irish89055: interesting, though it doesn't say which size V-8.......... best watched on MUTE..
justforever96: @liamcollister A 2-valve (per cyl) engine can match a 4-valve up to the highest levels, with the right cam. Forced induction goes a long way too. Nitro drag engines putting out 8000hp are still using 2-valve OHV Hemis. As for smaller vs larger displacement...a little engine can make the same power as a bigger one, but only at a cost in reliability. A 300hp 2.0L I-4 won't last nearly as long as a 5.7L V-8, if driven at capacity. Besides, 4-valve is so cliche these days...OHV is the standout now!
Pablo Rodríguez: Hi buddy pretty cool video.. Do you know where can I get a combustion engine planes or plots? This is cause I need to do the same work in SolidWorks and I don't know where can I get a 2D drawing with dimensions of a engine and I do not want to spend time measuring a real engine. Thanks
Sidney Pierrot: La grande simplicité de la mécanique Américaine, simple, mais d'une très grande efficacité... :)
Oldenways: @Rezaroth They could be this easy, but only Americans build still easy engines like this one. In many ways, it's better to have a simple engine like that, but of course it's no "masterpiece" or real engineering art. If you want really complicated and nearly robotic engines, you have to search for german ones. They are nearly impossible to repair for a hobby mechanic and become more and more complex. But in the aspect of engineering, they're the best. And in efficiency. But Ami V8's got soul^^
elmerhdga: @liamcollister .....you Limey fool, Chev V8's are way outside of your understanding, you are too young, too silly, too uneducated to go futher (sic.) with an explanation that you can't possibly understand.
xbigxredx2009: @liamcollister yea, and way the freak more reliable too =)
