| Ah,
the fine workmanship of GM engineering. Here's a heavy duty rated
crank-shaft by General Motors. It is found mostly in mini-vans and
ealier Camaro/Firebirds. It's internally balanced and carries a 981
casting number on it. If you want to get a heavy-duty crank for performance
application: ask for the one from a 1991 or newer Pontiac Transport, 3.1L
"D" Motor. This rugged crank has some weight to it. So less twist
and more power.
