Scat crank woodruf key

[ChiefDanGeorge]

I need to get a woodruf key for my scat crankshaft, and looking on Summit's site I see some reviews pointing out that the Pioneer set they have listed fits the OEM crank, however the Scat is different.  Just doing a Google search on 390 FE Scat woodruf key seems to show they key way is same size as OEM.
Anyone know for sure before I order one? They're cheap but I'd rather get it right the first time.

It uses a SBC (short, not like a stock FE key) key for the timing set and a regular square key for the balancer.

SBC = Small Block Chevy?

Scat crank uses a Pioneer PK9 small block Chevy keyway.  I find that I sometimes need to take a file and detail them just a small amount after installation to get the timing gear to slide on smoothly.  You should be able to find that key at any local parts house, hardware or 7-11 party store.

Thanks Barry!

A note about "keys" - there are keys available in several different alloys and size tolerances. The size problem can be "fixed" with a file, but the "hardware store" keys seem to be made out of Mud. The same mud as a hardware store grade 2 bolt.
Mcmaster-Carr has a variety of keys available, both Woodruff keys and straight key-stock, and they have a short chapter with an explanation of the differences in material and strength.  Big difference...

JMO, but I have to wonder why the manufacturer decided to use a Chevy crank key in a Ford crankshaft,  rather than just using the same key as Ford did. Do they not supply the required crank key with the crankshaft?
