as you know msd uses a bearing at the top side of the distributor and at the bottom of the distributor it is just aluminum, i have .006 side clearance i can move the shaft above the collar side to side in the bottom of the aluminum housing. msd said it is normal to have side clearance because when the dis goes into the block and into the pump shaft it will be fine. i dont trust msd. comp cams it all depends who you talk to. if some one who has the same distributor with the same clearance i will proceed to install the new cam gear.
thanks steve
