rent the video Two Lane Blacktop with James Taylor and Dennis Wilson. The
'55 Chevy had a truly built 427 and a real Rock Crusher M22 tranny. The
in-car shots are noisy from the howl of the transmission, which most
probably think is a blower, however, there was no blower on the car.

almost everyone has a "Rocker Crusher" in their Corvettes, even those with
the Borg Warner "rock crusher". Odds are he has the M20.

He could get grinding when trying to engage cold because the thick oil will
turn the gears enough to make things grind not to mention the synchros are
not slipping like they should to engage.
