I have a 97 Ford LN9000 with a series 60 Detroit that tends to make me moist all over when I start it. Been around Detroit's my whole life and it still turns my head when I hear one engage !
I like the last one where you can see the lifters all working. Only one person with hearing protection!
Lots of V-12s in that group (and German mechanics?) but nothing compares to that 7 cylinder radial with an inertia starter. ScreeeeeGrowl BANG BANG (cloud of smoke) ROAR! Better than those little blue pills..... The big Rolls was pretty bad-azz too.
