Annular Booster Install on a Holley 390- Allstate Threaded SLA

In this vid I go over installation of Allstate Carburetor's Screw in Annular Boosters, along with a brief description of Annulars vs other boosters, show how they compare to normal stock straight, etc. Website to Allstate: https://allcarbs.com/product/threaded... Allstate also has main bodies, Throttle blades and everything else to build/trick out carbs, peruse the website, cool stuff for creative minds!! The screw in boosters can be of other styles as well, more than just annular. Holley 390 HP- Currently not made, but specs are still up and can be found rebuilt from Holley, used, etc https://www.holley.com/products/disco... Previous vid of Horseshoe Intake not working out so well, lol.    • Jeep 4.0 Horseshoe Dyno Carb'ed
