Never blown one up, and have been racing them for fifty years. Have only seen four come apart, and one of those were when we were doing neutral starts back in the late sixties. Don't screw around and do stupid stuff in low gear and you will be fine. Keep after your stuff,, don't do burnouts in low gear, and check it close if you have a drive line failure. But, it makes for good pictures and gets the kids all riled up on this board.......I'd be interested to know of those "it's gonna blow up" crowd have dual street/strip cars, out blowing the street tires off in low gear to impress the kids on Saturday, bolt some slicks on Sunday and the trans comes apart on the first hit because they overturned the sprag screwing around the evening before. You guys can hit the panic button, but I'll just keep doing it the way I've done for 50 years. .
