Terry,
The cam spec's changed from a 230/236 to a 274/274 which changed the entire sound of the engine. The new Race Demon with the mechanical secondaries rather than the Holley 750 with the vacuum secondaries, made a significant difference. It does require some light feathering of the accelerator during the initial start up because it doesn't have the electric choke but the performance is well worth the extra few start up seconds!
