I also made one similar to my final setup. I will be track running the car and wanted longevity at high power, etc. I elected to go with the Dart block, SCAT 4340 crank and rods, and JE forged pistons with internal ballance. Anyway the dart block lets you go up to 4.185" bore. I elected to use a 4.125 bore and 4" stroke producing 427 CI. Note this would be a better combination (at 427 CI) then the 4.030" x 4.17" combo. I also added a 825 CFM Demon Carb.

This produced HP = 575 at 6000, TQ = 548 at 4500. Basically you get the torque of your original combo down low and the significantly improved power in the higher RPM (above ~4000).
