what makes the LT5 emit its unique sound?
when it winds up it sounds like a jet engine. i am sure you know what i am talking about.
the pushrod GM engines just make noise. the LT5 has a great sound to it.
is it the cams that make the sound or something else?

It's called WLT5@7000RPMs

but it happens in almost all rpm bands. even cruising in low rpm it winds up to a point and waits to be unwound further.
reason i am asking is because if i ever get the LT5 again this time i will have it modified to about 475hp or so but do not want to lose its unique sound, at all.

They sound better as the HP goes up

Jet Engine?.....Naaaah. More like a 32 valve Banshee from HELL, chains whipping and screaming! .......or... something else.

No one knows. Many have guesses. My guess would be the header-like, stock manifolds.

Just a thought but, what if those cams had cap like retainers instead of bolt on cam covers. Then the LT5 heads would have (Hemi-like) metal valve covers. That would amplify all that valve train noise and create a real racket.
It would also allow the bling boys to chrome them up cool like all those old Chrysler elephant motors.

But when it gets right down to the OP's question his thoughts are right on the money - the drive of the camshafts is responsible for the majority of what is heard. It's all chains, tensioners and the guides combined with the RPMs. It doesn't actually require many RPMs to hear the distinguished sound. I've a neighbor a good ways away and he can tell mine from nearly start up. If he's outside he's always been ready with a wave long before I go past his house.

New to the forum, but here goes.
I believe that it sounds the way it does because it has a 180 degree crank (flat plane) and corresponding firing order. This changes the engine balance and increases the RPM.
If you think about the sound of a twin cam 4 valve Ford Mustang Cobra engine, it sounds like a regular v8 (high performance but regular).
