only thing sofar (hillarious now),about 3 years ago at the nasc nat's i just got her spinniing up nicely when BANG!, then a lot of head scratching, only to find the cause, the harmonic balancer had cracked and gone off like a grenade, lucke had it that it only took out the bottom hose, cracked the power steering pump, put two dents in the hood and if you look closely at the inner fender in one of my pics' theres ducktape still over the hole it made there. 😳
