SandyC,
I saw your car yesterday. Spoke to Charlie about what it was in for and it sounds like what happened to mine. Sounds like the rings. Since Roush had mine out and went through it, things have been great. I know running the thin weight
oil they recommend, you will burn an little and loose a little which is normal but yours is doing what mine did. Is Charlie doing a leak down test? Keep us posted. They will take care of you. Mine is there to have the urethane motor mounts put in form Olthoff. But it's running great. Now I have the carb not the 8 stack.
