Not Ranked
I have two 505 FEs. One currently at 712HP, the other at 752HP. Both have the Scat cast 4.25 cranks in them. Both are limited to 6500RPM because thats where the power ended. The weaker one has been in my car and on the dyno repeatedly - perhaps 50 pulls and at least that many 10 sec 1/4 mile passes. The stronger one was my Engine Masters deal, and has been just a dyno queen (a few dozen pulls) - - it'll go in the car this summer. So far neither shows any sign of crank distress (fingers crossed).
