How about a good Drag race 904 build discussion

I have seen plenty of 9 second cars using a 904s.
My prediction is that the 904 is headed the way of the power glide in terms of aftermarket development. I don,t know how to post a link, but I just recently read an article about ATI recently developed a new roller clutch exclusively for the 904 that can take up to 1500 ft pounds of torque. They claim that the roller clutch is the 904s most unreliable component in big horsepower applications. I just recently received my w2 heads back from shady dell speed shop and I would expect very similar performance from my 68 dart that 70aar has in is cars.
I bet the combinations are very similar too.
One of the big trans builders claims on there web site that the 904 is one of the biggest drag racing secrets out there. Looking at tcs I am surprised at the amount of aftermarket support for the 904. Apparently some of the hemi superstockers are using the 727 with 904 internals.
But I here that durability is 8 runs. Yes I would very much like to see a parts list of the trans in 70aars 904. Am I spelling that right lol.
