Hey guys I have a z6 blocked mated to a y8 head but i am using the d16z6 distributor, cam, adjustable cam gear and the d16z6 cam timing cover. I cant find the p2p cam cover so i used the d16z6 cam cover to find tdc for the cam. So far the car drives ok but seems to be lacking topend. Is there another way to check if the cam as at tdc without the cam cover? Are the d16z6 and d16y8 cam cover the same? Thanks in advance.
