fastest small block

Was it a roller motor or one of the restrictor motors? Some make a bit more power but it seems most are around 830. What's the car weigh? 60ft? What is the converter?

I came so close to going with one of them but they require such a high stall speed it just didn't seem logical for a car I still street drive
with technology these day's they can make a converter that works great, I have a coan 8", I street drive the **** out of this thing, converter flashes 6800, this is a roller motor, makes 742 @ 8100 and 540 lbs @ 6400, 60' is 1.32, 3375 lbs car with driver.
