I just installed my Comp Cams XE274 cam and it says to install it at 106 degrees well this is my first time degreeing a cam or building a motor for that matter anyway Im pretty sure I went through the instructions properly that Comp Cams gave me and I ended up with my cam being at 105 degrees but here is my problem there is a little "slack" in the crank socket that I have and the wheel can go 1 or 2 degrees either way according to my pointer, should I not worry and leave my cam the way it is or is there something I can do to get a more accurate reading? I used the Comp Cams degree kit.....Thanks

Neal,
You will drive yourself crazy trying to get it any closer than 1 degree. Put it together and run it graemlins/thumbsup.gif

Thanks Bill took your advice and started getting the rest of the valve train ready to be installed and I noticed something else, with the timing chain on my motor I can move my cam back and forth in the block an 1/8" is this normal and will this movement be eliminated once I install my distributor?? Thanks again guys sorry for the Q's that have probably already been answered.... graemlins/beers.gif

Neil,
The back and forth movement is normal. If you want to, you could put on a cam button, but I personally feel it is a waste on most engines. The distributor gear is cut in such a way that the oil pump drag will pull the cam towards the back of the engine, along with the way that the cam lobes are ground. Some people will tell you you might get some "spark scatter" without the cam button, but I personally have never seen it. Keep on going, its almost together smile.gif
