I too read that article a few days ago.
I kind of put off doing anything like that as I'm seriously considering a procharger and calling it a day.
Was curious about the edelbrock as well and have seen it for 899, where I think Brennspeed will sell you the manifold, twin 60 mm TB and tune for 1700.
Figuring you'd need at least a 90 mm TB for the Edelbrock your getting close to the same price point.
Anyhow, all that, plus a converter and I'm getting close to what a pro charger would do and put me in the same et range, plus I don't have to pull the tranny!
