I have a 521 in my Cobra - its not "legal" to drive yet...but I have had it out up and down the block. I have a hydraulic flat tapped cam, the computer model says we should be around 550hp about 600 torque. It also has a T56 Magnum and 3.5:1 tru-trak. First gear was a little rough, on the edge of unusable. But 2nd gear was able to drive smoothly. And in 3rd as well. I was lightly pressing the accelerator, and it seemed to respond smoothly.
