It is about a lot of factors,mainly cubic inches.The bigger the displacement,the bigger the bang or thump.Comparing apples to apples.I for one prefer big blocks,first is the shear size of the block sitting in the engine bay.The other big one is a 500 hp big block is a better street motor than a 500 hp small block because of off idle torque.Finally,at 80 mph a big block can still torque the frame when you whack the throttle passing another road warrior.My opinion is based on a car set up to take full advantage of what a big block can deliver.By no means meant to take anything away from those of you that prefer small blocks.I ran them for many years in my toys.
