Smallblock intake manifold shootout.

Mopar muscle, done this comparison, and always suggest rpm airgap, for a cammed up, build, to most that inquire. And read, many times, suggesting the Inquirer to throw their holley intakes in the trash can? Curious about these Airgaps, I decided to replace the 72 spreadbore Thermoquad, setup, with an rpm airgap and new 780 st. avenger carb. What a huge difference, better low end torque, and top end. only downside- warmup time:-D just my .028)
