JM, I was actually kinda kidding. It would have been fun.
 
  I went into Kragen and the kid went back to get the tool for me to use. When he came out it was zip tied and was new. It was $30 so I just bought it. I got it pulled and the keyway in the balancer and crank look good to me. Even the woodruff was not bad. I bought an assortment of 5 and the correct one is in the package. So gotta clean everything up. I took the timing cover off and have some pictures to share. I gotta load them up and resize them. Forgot to protect the bolt head, ruined it. Oh well, if that's the worst thing so far, not bad. 

     Looks like the top gear is plastic? I took it off and inspected it and the other gear, chain looks loose, but only on ONE side. Then I rotated the engine a few times to line up the writing so I could get some good pictures. Just kidding, I'm dumb, but I isn't stupid.  ;D  I guess I will have to install a timing chain assembly and seal while I have it all apart, Right? What manufacturer should I use? Anybody got any part numbers?... Danny

DON'T PULL THAT CAM OUT !

well....there's your wandering timing....

New gears will come in your timing set...go with a quality roller. I had a 68 Pontiac with nylon? timing gear, to decrease noise, but they were garbage. Was not aware they used them in Z's ??? Get that engine at TDC ,check alignment "dots" on your gear set.

Use blue locktite on your pulley bolts during reassembly. Crank snout looks good, make sure no play between your new key and the keyway in your balancer. IMO,if there is shelve it for a new one, but doesn't really look bad from the pics

Personally,  I didn't see a need to replace the crank gear from his photos.  I'd replace the chain and use an all metal cam gear, but leave the crank/gear in place.   There was a time in the past that replacement crank gears were not as strong/good as the originals... not sure how that might have changed, but still didn't see a need to replace the crank gear...   IMO...

Ok guys thanx... I had heard years ago that ALL GM 302's had plastic cam gears.. I guess I just helped confirm... Here we go with the damn TDC thing again. If the lines line up right now, can't I just buy the new set-up and slide it on and make it up where it is? I think I put it at "0" on the timing cover perfectly before I took it off. By the way, Zero is TDC right? Sure would like to have a set-up that members have used and know is nice and strong, and a clean fit set.. I have never bought one... Danny

Gotta agree with Gary, crank gear looks good....and most likely superior to the well known ones out there, which have long since been outsourced. Quite a bit of writings on this a few years ago by engine builders.

As far as I know Cloyes maintains a good rep,as well as Lunati. We run a PBM , more than you need for your application.

About that #@#! TDC thing, pretty important thing to have a handle on when you start tearing into these. Yes, can put it back together exactly the way it came apart, as long as it's exactly the way it came apart.

Pick up David Vizard's book on " Rebuilding your SBC"  take a read through before you proceed, just a suggestion. Great reference material, jot a few notes in it on your engine. Jot a few notes from John Z's articles in it and some some of the info out of these posts pertaining to 302's fine tuning in it.

They make a distinct, beautiful sound when they are tuned correctly and screaming, but are not  forgiving being a performance engine if poorly maintained.
