Haven't been doing it that long, (only 29) but I have been doing it to my Muncie
M22 for over 8 years.  It's all in timing.  Your are right, syncros don't like
the abuse, especially behind a 454, shifting at 7500.  Muncies inheritantly eat
3rd up first for some reason.  Jerico makes a 4 speed that is clutchless. Can
exactly remember how it works, but it somehow during the shift locks both gears,
and then slides off.
G-force also makes a 5 speed shiftless trans.  Looking into replacing mine with
one of G-forces.
