So you think a girdle will help stabilize crank walk? I can show you dozens of pics with massive destruction of guys using girdles. There are pics on Stangnet, Corral and ModdedMustangs showing how effective a girdle really is. Its only effectiveness lies in the fact that it keeps all the peices from shooting through the oil pan and onto the track. Let me guess, your a believer in the valley girdle as well. And not trying to knock you off yoru horse champ, but your a machinist, Not an engine builder. I take my block and crank to you to cut or polish, not to put it together. Just like I wouldnt take my car to a muffler shop to get A/C repair work done.
