No its not a common problem. Did the whole plug come out or just the white part the wire goes on? Champion plugs have been known to have this problem.

THe whole DAMN plug popped out.
His Mechanic ( a buddy of mine) says that it apperently happens often on the GTs...... hmm.. Too high compression for the heads?

Then it should have taken the threads in the head with it. If the heads are aluminum you should still be good to around 16.1 compression. Probably alittle more. Seems like I have heard about the 4.6 mod motors blowing plugs out. If you change plugs alot in the alum. heads and dont use antiseize that can happen from removing the threads everytime the plug comes out.

Plugs do not just blow out of any head unless it is not torqued or the threads have been fubar'd.

I agree with Bud...must use anti-seize on the plugs with aluminum heads.
