Is the 8" ATI converter an off the shelf 5000 stall? Or do you need to custom order it? Seems like a very nice piece. Would it be a good street/strip choice for a 360 with a 292 purple cam and 3.91's out back? I currently have an FTI 3400-3600 stall converter.
Good street set up. Track wise, it lacks.
