Hughes Engines Tech Center: Six-Pack Porting Potential

Chrysler may have been one of the last to try out triple carburetors but, when they finally decided to take the plunge midway through the 1969 model year, they sure did it right. Those first 1969.5 Road Runners and Super Bees all featured the now-famous trio of Holley twos atop a slick and seductive chunk of aluminum by Edelbrock.

Unfortunately, that lightweight intake was short-lived as ’70 models had cast iron versions phased in early on. But Edelbrock wasn’t so quick to give up on that awesome piece of airflow and they even still offer it some fifty-plus years later as the CH-6B.

Not only that, but a precious few performance Mopar shops like Hughes Engines offer some “hidden enhancements” that can really make those six barrels sing. Three tiers of porting are available for six pack attacks, each tailored to throw more air at some hungry cylinders when the throttle blades tip.

A deep match (P/N HUG 2475 DM), street/strip port (P/N HUG 2475 SI), and the “P.W. Special” (P/N HUG 2475 S3) range from mild to wild in terms of material removal and massaging. And, for a couple bucks more, concerned customers can even get before and after flow sheets to confirm CFM improvement.

Hit up Hughes online or at (309) 745-9558 to see if they can help sneak a few horses into your stable too.

Kent Will

Kent grew up in the shop with his old man and his '70 Charger R/T. His first car was a 1969 Super Bee project when Kent was fourteen. That restoration experience lead to pursuing a degree in Mechanical Engineering and a career in manufacturing. Since then, the garage has expanded to include a '67 Satellite, a '72 Scamp, and a 2010 Mopar '10 Challenger.
