Mast and Lingenfelter are both popular, and given the conversations I've seen/heard, they stand behind their products pretty strongly (in other words, they know what happens when you race). There are tons of good crate setups out there, including the GM PowerParts stuff that many guys on here have used. You would of course have to source your own TB-style intake that way . . .
For some odd reason, I like the big plastic box sitting in my car's engine compartment. It barely fits under the hood, and it so isn't supposed to be there . . .
