How true that is. It’s been said over and over again, printed over and over again, dual planes are best for street & street strip. Single planes are best left for race engines.
Everyone will see a dyno test and fall over themselves to use the single plane because it made 40+ hp more than the dual plane. Then they curse it out for its less than desirable street manors, slower 60’ & crap mileage.
What’s even funnier is when people start to throw stones at the performance under 3500. With the single plane, you should be ignoring it completely because a single plane is only at the beginning of its power band at a Minimum! The camshaft should be matching that rpm range as well.
