Take a step back into the history of hot rodding for a moment. Way back before electronic fuel injection was available as a standard induction system, carburetors ruled the roost when it came to taming the mean streets. We’re talking the golden era of musclecars, when the factory didn’t think twice about slapping a pair of four-barrel carburetors on top of a factory showroom model.
In 1967, Holley supplied the 427 Corvettes with three two-barrel carburetors. One camp called it triple deuces, another called it the six-pack, and GM called their multi-carb setup the Tri-Power. It found its way on various GM models during the musclecar era, and seeing so much carburetor fill the space between the water neck and the distributor was pure beast-mode.
Although many modern hot rodders have elected to convert over to the driver-friendly throttle body fuel injection conversion kits, there are still many old school cool holdouts that still love the look of the Tri-Power setup, and the feel after kicking in that extra pair of carburetors when the pedal is romped on.
Holley’s Blane Burnett shows us a Tri-Power setup in the video above that you can buy brand new today with the same kind of underhood magic that the Tri-Power provided gearheads with back in the 1960s and 1970s. Available with either a tumble polished finish (JEGS part #510-300-522) or the old school look of dichromate finish (JEGS part #510-300-521), both kits include a new Weiand dual plane intake manifold and three polished air cleaners with reusable filters (JEGS part #510-120-105).
As was the case for most of these setups, the center carburetor was your cruising carburetor, a little larger cfm than the outer two, and when it was time to put up or shut up the second and third carburetors would kick in on a progressive linkage, providing the extra grunt needed to turn on the power.
The center carburetor is a 350 cfm, while the two outer carburetors are 325 cfm each. Ask any old schooler and he or she will tell you: there’s nothing like hearing and feeling the power when the additional four barrels kick in on a Tri-Power.
If you’re still hooked on old school cool and don’t want to spend weeks searching for an old setup, check out what Holley has for you on their website in the carburetor category. EFI is great, but nothing beats the look of a Tri-Power setup when you pop the hood at cruise night. There’s going to be a crowd – just like the one on top of your intake manifold.
