The 292 gets it's torque about 1,000 rpm lower than the 283. This is all due to cylinder charging. The little monojet 1 barrell has a very high intake velocity at low rpm. Low rpm cylinder charging is what makes it torqey. The same is true for the GMC V-6. Tiny little carb on a 305--351---401--478
The Quadrajet is an attempt to get the torque with small primaries and still have lots of high rpm with the huge secondaries. Same idea for the Thermoquad. They also made V-8 manifolds with individual runners for the primaries seperate from the secondary runner.
It is all about intake port velocity.
I have a 317 lincoln engine that came stock in a F-900 Marmon Herrington. I found a super deal on a 4 bbl manifold but, I think that it would kill the low-end torque.
It's a trade-off between low-end and high-end torque.
