Most likely. It's just a photo I pulled searching "fuel injected small block Chevy photos". Many "roundy round" oval track cars ran very long velocity stacks for probably a good reason. Formula 1 cars have/had an affinity for velocity stacks also. According to Gordon Jennings "Two Stroke Tuner's Handbook" the long velocity stacks tend to eliminate secondary intake tract resonances that upset proper fuel metering. Short velocity stacks may look cool but may in fact interfere with proper fuel metering. Bottom line is you are hard pressed to beat the O.E.M airbox/air filter set-up.
