Coincidentally we have just finished reverse engineering a set for this application for Mike Shally. Mike was nice enough to supply us with patterns specific to the 1968 GT350 Holley and aluminum intake configuration. I wish we had the benefit of factory blueprints, but for over 30 years we have relied on great customers/friends to help us through the endless applications and variants to add to our selection of replacement tubing. All this goodwill has helped us grow and make better parts. Hope we can help Corey.
