the girdle minimizes or eliminates cap walk depending on how severe it is. we don't use the main studs to tie the girdle down to the caps. also our caps fit snug with the bottom of the girdle after a little machining.

last year we even made a girdle for a prostock hemi that had cross bolted caps. so we redesigned the original caps to use a similar concept as our big block caps. so he had main studs, cross bolts, and a girdle.

even with the cross bolted mains there was still tons of evidence of cap walk on his hemi. he hasn't pulled the engine out yet and I'm hoping he sends me some pics of the bottom end when it gets freshened up. i'll keep you guys posted.
