Engine Noise When Cold

I have a '95 Dakota SLT CLub Cab 4X4 with a 5.2 L V8 and a 5-speed tranny.

When the truck is cold, the engine noise is quite loud during acceleration.

It sounds like the engine is redlining, even though it's only revving about
1500 RPM and going about 15 km/hr.

This noise only occurs when it's quite cold out (below freezing or a few degrees
above freezing) and goes away after a few minutes.

I've heard this sound in a few other vehicles as well, notably Chevy V6 Astro Vans
and Isuzu Rodeos (which also have a Chevy V6 in them). The sound is like a large
fan running full blast.

I'm assuming the noise is intake howl that occurs while a certain flap or valve
is open during cold running. I'm not really worried about it, but I'm wondering
if anybody else has this problem and figured out what it is.

My truck is also a Canadian version, if that makes any difference.
