I've seen cars (of all brands, not just Mopars) due neutral drops or starts at Orange County drag strip, the old Irwindale 1/4 mile strip. The first time i saw was at Mickey Thompson Fontana Drag City in Fontana, CA in 1964.
Have you seen the picture of the AA/Fuel altered dropping, blowing, the complete crank assembly and the bottom of the block out of a early blown fuel Chrysler firepower hemi at Orange County drag strip in the late 1960s
I wish I had found and bought a copy of that one, but I didn't
it was an excellent picture, you could see the oil coming down with the parts. I was told it had a clucthflyte in the car also, you could see the flywheel on the back of the crank also
