Is the crank/pulley keyed?

[nick112288]

Good afternoon. I'm doing some reading and I'm trying to figure out if the Mustang crank and pulley are keyed together? Or is it not a concern on these engines unless going big power?

I've tried doing some searching but didn't really find anything other than people mentioning double keyed on high power applications. Didn't indicate if that meant stock it is single keyed or not.

The factory crank and pulley are single keyed. Double key is recommended for high HP builds.

What is considered high HP? I would have a goal of about 600 at the wheels

The crank cannot be double keyed when in the motor. This is a process done during an engine build when shooting for the moon and over 1000hp. We warranty our complete supercharger kits at over 600whp. You do not need this.
