well, i just purchased all 4 caps from another member on the board. i was using the rjc girdle when the crank broke on my last motor. i am trying to decide which to use so, i am looking for opinion to help me out i have both of them, so $$$$ isnt a ?(for the initial purchase) i know i gotta fork out some cash for the line bore on the caps,and i would also have to go to arp to get a bolt kit for the girdle which isnt cheap either! sooooooo lemme know your thoughts or experiences---------this buildup is a 109 block w/ 500 rwhp--give or take a few...
