Converter. Trans brake questions.

LOL I have a friend who got the family fortune stuck up his *** and you know bought the house in the neighborhood he doesn't belong in and the cars he doesn't deserve whatsoever. Again long time high school friend and he had a 2010 special edition Corvette. Of course this was back when my duster had its 318 in it and he said all the time he would meet me at the track anytime and blow my crap away. Well the day finally came and of course I left the light like a person who's been there before and of course he left the light squealing tires and missing gears and of course had way way more power than I did and caught me and passed me just before the finish line LOL of course the best he could muster in that badass Corvette was a 14-2 LOL and also of course when I showed him Time Slips of the 13-7 I was doing after a little more tuning and practice he never came back to the track.
Well now I just spoke a little too fast I just remembered a couple years ago he bought a fully cage fully done El Camino with a modern LS1 with nitrous blah blah blah. Of course it had the fully tuned 4-link suspension also blah blah blah LOL...
He comes over one day with his store bought car gleaming showing me his single time slip LOL that revealed a terrible reaction time and a piss-poor 60-foot Time for what he has and pointed out that the real thing is the mile an hour at the end of the track!? I laugh and I go pull off my garage wall of this huge monster stack of Time Slips walkover to his El Camino where he's gleaming over his one-time slip and show him my stack as you can see his shoulders dropped and then I show him the same 119 mile an hour time slip that my old beater did LOL he certainly got drained of all his enthusiasm at that moment...
