Waste of a good short block ?

Aside from proper balancing, there is not much difference between a cast and a forged crank anyway. It takes a heck of a build up to compromise a cast crank!! A buddy of mine has been running the same cast crank motor since I sold it to him over 5 years ago. He's into the 11's now and HP's up in the 500's somewhere, no problems!! And he runs it!! Geof
