Holley vs. Edelbrock, Tri-Power vs. Dual-Quad!

Dual quads! Three deuces! Eight barrels! Six jugs! The lore of multiple carburetors runs deep in the hot rodding world, and in the muscle car era it was common for the OE manufacturers to up their cars’ performance and image with either two four-barrel carburetors (a dual-quad, or eight-barrel) or three two-barrel carbs (known at GM as a Tri-Power and at Chrysler as a Six Pack). These days, everything old is new again, and both Holley and Edelbrock are offering complete setups to put multiple carburetors on your small-block Chevy (Edelbrock also has kits for many other popular V8s). In this episode of Engine Masters presented by AMSOIL, we will compare the price, the tuneup, and the power of the Holley Tri-Power setup (part number 300-521 with gold dichromate carbs) to the Edelbrock Performer RPM Dual-Quad manifold and carb kit (part number 2025 in a satin finish), all on our Blueprint Engines 383 stroker that makes 476 horsepower with an 850-cfm four-barrel. Can the multi-carb rigs match that power? The Edelbrock dual-quad uses two 500-cfm carbs, and the Holley has 325 cfm in the middle and 350 cfm on each outer carb. The Holley setup is more true to the muscle car days and the Edelbrock is more of a modernized design. We’ll assume you’re gonna pick one over the other based on personal preference, but this video will help ensure you make the right call for your own car.

  1. I’d take the eldebrocks based on my experiance with holly carbs over the years.

  2. Edelbrock is the only way to go, holley has way to many problems,had in the past and would never own one again

  3. So it seems to me to save money the single 4barrel and high rise would be the way to go less money and same HP but if your going for the more hot rod looks the three Deuces could be the other way to go

  4. Holley carbs are a basket case of problems. Fix one thing on them and two more go haywire
