That Aussie intake is a nice intake. IF I was just doing a basic bolt on and mild cam step up, the 2bbl. unit I would use. That oughtta work really nice.
Which 2bbl would you use? The holly 500cfm? or a different one? I'm planning on getting a new intake manifold (I would actually like to get that aussie intake) and new headers but yes my main priority would be the carb and cam set up.
