We are getting ready to put our 400/512 in...Basically the same combo from 440 source but with light weight crank in a 400 block.

We are hoping for a 9.59 with it....We will see. Can't wait to see if we hit 140mph with it. I was super impressed when we went 138.5 the other week with the 440/512....We have seven seasons on that and its due for a good freshen up or I may sell it and build an all aluminum low deck 512...We really like this and the 440/526 combo from 440 source. They make a ton of torque.
