Identify this Stroker crank?

[bignick]

I just bought a 340 based stroker and it has penstars cast into a couple throws. I haven't taken the motor apart yet but it does have eagle 6.123 H beams and custom Diamond dish pistons in it. I don't remember seeing penstars cast into my last 4" Mopar Performance crank but that was in 2000 and I'm not sure how old this crank is. Any ideas?

On MP stroker cranks...seen most with part number stamped on the front side of the front counter weight

I tried to find a part # on the front throw and it has none that I can see. Only some machine shop #'s that and stamped in.

roll the motor over and measure it at the piston.

Baxter I know it's a 4" crank because I already identified the piston and rod. Piston is a Diamond custom with a Compression height of 1.457 and it has Eagle 6.123" rods. My question is has anyone seen these cast in penstars on Mopar performance cranks or is it something else?
