[QUOTE="justa03, post: 12099791, member: 32157"] I know this topic has been covered a few times about the process of degreeing the 4V. So I put Crower stage 3s in my car about 4 years ago, car never ran right couldnt get it tuned right. Tore it apart almost 2 years ago and now getting back into it. In the process of degreeing the cams. I lined up all the dots and links for a base timing. From there I followed Comp Cams centerline method and my results are as follows, RH exh 118* int 103*, LH exh 107.5* and int 116*. According to the cam card centerline should be at 110* Has anyone that has done this or experience with this have seen them that far off before? Im planning on shaving the keyway and using ARP camshaft bolts to torque the cam gears into place. The timing chains were tight as I had a clamp on each timing chain guide to tighten them. I checked and rechecked and kept coming up with the same numbers. Just wondering if I am doing this right or is something wrong? I also contacted Crower on this and was given Dave Crowers direct number and was told to check tappet lift at .006" and then valve lift at .050". Does this sound right to anyone one? Dave was telling me I have to check at .006" tappet lift to have zero lash and I am using MMRs solid lifter. Any help or insight would be greatly appreciated. Thanks, Dan :beer: [/QUOTE]
