Sound difference between hydraulic vs solid camshafts

[fordracing65]

What is the sound difference between a solid vs a hydraulic roller camshaft if the specs are the same, 482 fe for example????

[RICK LAKE]

fordracing65 Mufflers, camshaft profiles, high compression, and even tie bars for hydro roller lifters all can be heard. Motors with Webers when setup right can heard a sound pitch change when they clear out.
Are you looking for a nasty idle, Loud exhaust, or bug killer?? A little more info would help on the noise. Rick l. PS A solid camshaft and hydro roller camshaft don't have the same ramps for the profile and will give the motor a different tone with every else being the same. Hydro are really the way to go. I have run a set of crane hydro roller for 16 years and no problems with high oil pressures. They run like solids if setup with min valve lash.

Pete, you need the hydraulic cam......

Remember, for most of us, these are just toys. Grown up versions of the Hot Wheels cars we played with as kids. If you look at it that way, then you don't spec your car to squeeze every last ounce of power or performance or mechanical efficiency out of it. I chose the old SFT cam of mine because I like the noise it makes, leather because I like the smell, six-pin drives because I like the looks of them when I pull the wheels. These cars are nothing more than fun little diversions -- just treat them that way.

IF your question is about why a solid cam has tappet noise where a hydraulic cam is quieter----------The hydraulic lifter is in constant contact with the cam lobe---solid tappets need to have valve lash clearance so the valves will completely close when the engine is cold, and depending on the cam/engine/manufacture will have clearances ranging from around .010 towards .030--------some companies was around .012 to .016 where Ford was I think .019 on Y Blocks and .025-.027 on the FEs------

So the cam wouldn't slap the tappet, cams were ground with a "clearance ramp", an area of the lobe that gradually took up the clearance over a few degrees of cam rotation--the FEs were destntively louder(so much so that Ford Quickly converted to hydraulics in the 332 /352s very early 1958----they identified these hydraulic engines with a spot of orange paint on the left(I think)side of the timing cover----

This post adds absolutely nothing to this thread.

No, my post is directly on point. FR65 is considering making a decision based on the sound of a component. You only do that with your toys. Fortunately, that's perfectly acceptable here... and I politely pointed that out.

But that's how you get to 14,399 posts-silly!!

FR65's question is about the sound difference of two types of cams. "You only do that with toys" is off-point.....again.

Actually - I like this comparison. And then you can throw in mild steel tubing headers and end up with.

No it's not. Note Blykins response of "you need the hydraulic cam." The whole point of this hobby is that these are toys -- it's not what you need, but rather what you want. Just like being stuck inside of Mobile (with the Memphis blues again).

Sound check please. Testing 1, 2, 3.

Vector1's response was on point. Yours? Not.

Hmmph. Well, in that case, I think the sound is more like "oogachaka, oogachaka, doo-wa, diddy, diddy." Or, the OP could just listen to the beautiful beat of my solid lifters in the link in my signature.

My job is to make qualifications based on the customer's testimony, then build the engine.

Pete and I have talked many times, and although he hasn't ordered an engine yet, he has emphasized the need for durability, reliability, and the ability to drive long stretches at a time while cruising.

My recommendation would be the hydraulic roller...since it's a little more than a "toy" with this type of reasoning.

Alright, nothing wrong with that. But I'm still putting you in the "debutante" category and not in the "Ruthie" category. Especially since you don't have a honkey-tonk lagoon.

Dude I have no clue what any of that was supposed to have meant.

Ah yes the sound of a 60's muscle car...LOVE IT!!!!!!!!!!!!!!!!!!!!

Brent, just don't bother asking. I stopped a long time ago. He's baiting anyone to take him up on his nonsense. It is just not worth it the internet server space.
