stall speed help

need a stall speed for a 904 trans.. 72 demon with a 408 stroker, 529 torque and 472 hp, run on street/strip. 3.73 rear gear for now but going to 3.23 soon.. 265/60/15 tires

As the others have said, Go to a professional for the best match. Those 904's are light and transfer lots of power without much parasitic loss. I run a 408 with slightly more output, and a lower 3.91 rear gear set with a 2.76 to 1 first gear ratio. It also has a .67 overdrive for practical daily driver use. The only way its really predictably safe to drive on the streets is because of todays tire technology. I highly recommend the Nitto Drag Radials. They work incredibly well in wet and dry conditions, last me for several years and are reasonably priced. They also have a 186mph speed rating.
