well i would like to let everyone know that i have found the one and only true fix for cam thrust surface on the front of the block being worn. we have found a thrust roller bearing that we put into the front of the block by using a c&c program that lets us machine and countersinking it into the block. you can find pictures at my link http://community.webshots.com/user/boost2311 or if you have any questions or would like to send your block to us and have us do this for you give us a call. you can talk to Cliff at Cliffs auto service (520)546-3800 or email him at cliffsauto@directway.com we are located in tucson arizona. I will also be bringing one of our blocks up to vegas for the west coast nationals if anyone would like to see the product up close.
