Hughes Girdle ! Opinions Appreciated

I'll 2nd the girdle is a waste of money and time. Run a lighter rod and you're fine with stock caps with studs. If you want to retain the H beams, you can replace the #1-4 mains with billet and studs. Lighter parts are the ticket to making any of the factory blocks live. Studs address the caps moving in the block. Billet addresses the caps deforming.
