if i recall right, the guys at roadkill sprayed a worn out, junkyard 68 cuda 273 into the low 12s, straight from the junkyard. That's pretty quick for a junkyard motor, the 360 would have to be good for 11s on spray right?
And there was the one that they did that tore the piston top off from not resizing the rings in the "How much nitrous can a stock bottom end take?"
I don't remember how much they got before it blew, but it was the ring gap that killed it.
