There was a member here a long time ago that had a kit installed on his single port, I think his name was rancher_lee. From my research, the kit will work, all you have to do is modify the intake tube, and get a tune. The tune is the tricky part because not many tuners have experience with tbirds. BTW, I just sold the vortech kit that I had a few weeks ago. I just don't have time anymore to experiment with unique mods.
