Help me ID this stroker crank

I am looking for help to identify a crank that I have.  This crank was purchased by me
approx 15-18 years ago.  I can't remember who/where I got it from.  It is a 4340 460 4.500 stroke
with BBC rod journals.  I did contact Ohio crankshaft and Scat with pictures and phone
conversation and both have determined it's not theirs.  I have been cleaning out my shop
and came across this and thought maybe someone on this forum could help me.
The link below is to a folder which contains pictures of this crank.
Thanks in advance for any and all help!

Looks like an RPM International to me.

Looks like a RPM 4.5 stroke 4340 forged steel to me you can call RPM and they can tell you if it is for sure.

Thanks for the help gentlemen. I placed a call to RPM and talked to them, which was very helpful......but not their crank.
Per the guy I spoke too at RPM I followed this call with a call to Tech Support at:

CAL RACING ENGINE PRODUCTS (CAT PERFORMANCE PRODUCTS)

Low and Behold after a nice conversation he positively ID'd it as one of theirs, although they
no longer produce this crank.

So my quest is complete. Thank you for the help!!
