Does any body make a high performance intake manifold for 1980 Pontiac 4.9 liter v8?

I believe edelbrock makes a selection of intake manifolds for the 4.9. I have a carb 4.9 in an 81, I'm thinking of getting one.

The 301 (4.9) Pontiac was pretty much a one off engine. To date, I know of no one that makes any type of performance intakes for it. Most people rip out the 301 and drop in a 350, 400...whatever.....since it will bolt right in. The only options you have is the factory 301 4bbl intake......or going to the T/A turbo unit.
