I have never had this problem before and I've been in this engine many times.

Only thing changed is the use of a 2 step at launch. ( 7000)

There were also 3 lash caps that were shot ( pitted and erroded in middle ) as well as the bearing retainer in the cam button broken. It was also welding ( fretting ) to the face of the crank gear. The lash caps were observed to be "good" just 2 months ago at a spring change.
One other change was to a .120 wall pushrod from an .080 wall.

Timing chain was also very loose...............these conditions are all unusual for this engine. One more thing , the interference fit on the valve springs , Comp 944 , was looser than they used to be. They tell me they loosened the fit because of heat.........they slip in now , some seem almost too loose................dont know if this is related to anything though.

This is a stick car , the 2 step is a big help for cutting lights BUT , does it have to go.....................is it the reason for my issues?
