Crank Pulley

ive put a crank pulley on a few of my chevy trucks with a nice gain in performance. Wondering if we can use the same pulley as for the 5.3 or 6.0 truck motors

It does show to be the same part# for both applications in the GM catalog so I would say yes

Norcal:

What pulley swap are you considering? Just the crank pulley, or crank as well as alternator?
