Saving The older aluminum rods by reducing the RPM at the end of the run was the main reasons most drag racers like to push the clutch in or stick it into nuetral
Or to take a spark plug reading.

My car probably should have had a chute on it even before it went fast enough to require one, lol.

Huh, some interesting comments and thoughts, but few of them based on fact. First, the reason some valve bodies have a "clean" neutral is because they are reverse pattern. So to be able to neutral the car and not go back through the gears, the "clean" spot is added. Has nothing to do with other things applied for drum speeds of whatever.
You find reverse in the lights?.........why don't you have a shifter with a reverse lockout.
You need engine braking to stop at your track........use that pack thing you have mounted on the deck lid.
Engine braking is uneeded wear and tear on the motor. You'd rather do that as buy brake pads, that's fine.
If possible in the car I am driving, it gets put in neutral and the motor killed at the stripe on every pass. Coast to a stop, gather the chute if used, take my gear off. Then fire motor and drive back, or wait for tow vehicle depending on type car some of us don't have cars anywhere near fast enough for a chute...lol If your car is fast enough that you NEED engine braking to stop on the track where you run. You either need better brakes or a chute............it's that simple

Or to take a spark plug reading. Good observation. If you don't have the ability to neutral the trans and kill the motor at the stripe, there is no need for you to ever screw a plug out and read it. Because after you stop the car with engine braking, the plug reading means zilch, nada, nothing. Waste of time to even look.

Or to take a s6park plug reading. I considered that. Need to get a friend to pull me back to the pits as no way the mini trail will pull the car. LOL!

Doesn't matter about the extra plug unless you neutral the car and kill the motor. Leave it running on deccel and in gear, the plug read is junk Trans lubing under those circumstances?

It is the same as carving up a block for oiling mods--no real gain and a great chance to screw something up pretty big time--727's do NOT lend themselves to neutral in the lights without some real risk and...the gain is just very small if any for average guy--plug readings? Oh boy...bracket racers jet very different than best HP dyno deals--you jet by a totally different set of standards than you get by reading a darn plug--you read your TIME SLIPS and weather station--it must be lean enough that she don't have enough fuel to take advantage of better air so your ET remains more consistent--plug readings are no help here oiling mods ruin MORE BLOCKS than they save--
The racer that waxes your behind on bracket night knows all of this, runs same plugs a year or two without ever taking them out and does not give two hoots about a neutral in the lights--it is usually more of a lock the wheels in the lights from my observations

Even before I had a roller equipped trans they looked just fine when inspecting. In Vegas we coast the downhill return road most the way engine off. Clean N from Pro Trans for me....

Until there were clean neutral shifters/valve bodies for 727s, A&A said a big NO to neutraling the trans at the lights for the exact reason Monte stated.
"use it 'till it breaks, replace as needed"
