Best intake for a supercharger...
I am rebuilding my 350 Iroc next summer. If I do supercharge it, what is the best intake for this? Any help is appreciated.

The better flowing the intake is the better it will be.
You can use them and make good power, but you don't need the long indpendant runners like a stock TPI.
The supercharer will make more than enough torque with short runners and will make more horsepower too.
A short runner manifold like a mini ram will work very well probably making the most power, if you want to stay with somethig a little closer to stock configuration a super ram will be fine. Or for an even more "original type configuration", you can also use a stock ported plenum with deeply siamesed runners and/or siamesed base too.
You can use all stock type components with good results too. Especially so if ported. Boost helps make up a little for intake manifold short comings.

a shorter runner intake will usually make more hp at a LOWER boost reading with the right cam
where as a longer runner intake will make the same hp as the short runner, BUT at a higer boost reading because you have to really push the boost through the long runners, again matched to the right cam
point in case:
local 88GTA that went 10.80s on 17psi with a 383 and STOCK base, runners.
if he had a miniram he'd probably hit the same number with about 12-13psi all things being equal with suspension/cam/converter/gear selection
