One other symptom to add to the diagnosis before we pull this thing apart.

You can turn the crank pulley about 10 degrees in either direction although it appears the cam pulley does not move when you do so. Last, you can also move the crank pully towards the block by about 1 to 2 degrees -- it has that much play in it.

Really crazy that this car ran great one weekend and then went pop this quick. Par for the course with our racing efforts I guess.
