Dan,
Art Car makes one that is SFI approved. Pittman hasn't installed it on his car yet so if you would like to see it let me know. We ran Pittman's car on Wednesday and it started to come around. It ran a 10.41 at 132 with a 5 disc Precision converter that was wired wrong and wouldn't lock. Converter is very loose (4000 stall) and purchased that way to work with lock-up.
