header / intake carburation question

I was watching the Barret-Jackson auction last night. Saw a 1961 Chrysler
300 G sold. It had (twin) carbs monted as wide as possible in the engine
bay - pretty much on each wheel arch. Then there were long, long, long
intake runners. They looked like the horns of a water-buffalo.

The show's presenters voiced the opinion that the configuration had an
effect on HP & torque - a theory I've heard before - talking about plenum
height or volume on a Nascar show, I think. I've also seen the GM
performance parts talking about plenum characteristics and the effect on
(mid-range) torque & high-end HP.

2 basic theories (or perhaps the same one, badly explained), mentions
resonance/inertia in the flow of fuel. Does anyone know of a GOOD
educational source (i.e. somewhere that fully explains the facts, without
trying to sell me anything), please ?

THX.......

P.S. I don't build 'em, I don't design 'em - I just drive 'em like I stole
'em.
