Good afternoon John,
What other Intakes have you tried on the engine?
I did see that was the intake you are currently using. If that's the best one you have found then bolting on an adaptor and trying to move it some on the plenum opening might help. I would probably try that while on a dyno test. I believe Edelbrock used to make a similar adaptor that could be Heli-arched on instead of bolting on.
Moroso used to make a cast aluminum Adaptor but it was about 2' tall and wide open. I don't know how much carb to hood clearance you. In the past certain engines responded better to a little bit smaller runner sized intake manifold even with ported Stock cast iron cylinder heads. Then having the runners and plenum ported ( in the intake manifold ) and blended to finished it off. The Power band of the engine and its cubic inch's will have a direct effect on the manifold choice, how much carb to hood clearance do you have?
What is the thickness of your current adaptor?
