Thanks for the ideas, I'm busy at work, hopefully have more time to look on the weekend.Again, thanks.

Ok, I'm not guaranteeing this is the problem, but it sure looks like it. The cam is moving back and forth a little under 1/8 inch. The pictures show what effect this has on the timing change, I'd say it's moving almost 3/8" at the rotor, extended to the cap edge. Next I've gotta find why the cam gear isn't going on further. I think it's the dowel pin. ....Yikes I tried to post pics but I don't know how to resize them to fit.

Weird deal... I tried another timing set I had in the garage [used, but good shape] I have virtually NO movement at the rotor, when cam pushed or pulled. I don't know how it could be the cam sprocket, unless they machined the part that snugs to the cam thicker. They are both Cloyes multi keyed double rollers.

Are they the same part number.?
There are two part numbers for the SBF.

I believe they are, both the same C609 is stamped on the cam sprocket. I think the problem may have come from the fact that I used a thin washer between the cam sprocket and the thrust plate, it must have come with the T set. I think it ate away at the back of the sprocket. You can see its been shaved down quite a bit. The cam end play with Tset from garage is .006 +-, the one on the car had .09, not .009, but .09! Yikes!

The washers are not always required. Always check the end play and that will help you decide if you need the shim. There are also 3 different styles of retainer plates that are used on SBF's.
