HRD - I don't think that's an apples-to-apples comparison. How's a 426 N/A Drag Pak with a 270+ at .050" cam pull at 2000 RPM under a load? And how would it behave if it was also retro-fitted with a carb and old-tech mechanical-advance ignition?
The original question was port size vs aplication, this is a very exagerated example of really big ports in both size and flow for the CID but still makes plenty of TQ in the aplication... Now we have a 485 hp SAE Net 392 with plenty of low end TQ.
