Drawing from the
deep history of experience at
Callies, our Compstar
engineers have been able to
combine the best
characteristics of
performance crankshaft design
into the Compstar
"Compweight" for Big Block
Chevy applications Produced
from 4340 material that is
triple heat treated and
stress relieved during
machining. Compstar BBC
Compweights will remain true
during severe duty use.
All Compstar Compweights are
center counterweighted for
reduced bearing loads during
high RPM use. Machined with
.125 journal radii and
conventional straight shot
oiling, these cranks offer
simple durability. With all 4
rod journals drilled,
Compstar BBC Compweight
cranks weigh in at 75lbs or
less. Compweights are fully
deep case nitrided.
