Help with 4.6 crank I.D.
 

Hi. I have a Ford crank here that I believe is for a 4.6. It is forged & looks like it has been balanced. Has 8-bolt flywheel mount. Has QQPLO-20+ & 144C7415+ in ink on the flywheel mounting surface. Has W-2242 & F75E AE cast into the crank. In the last counterweight it has 23-05-01, 90W, & 21.41.04 etched. On the front counterweight it has 60C130C etched. Any help as to what this crank is for would be appreciated. I am guessing a 4.6 Cobra?

Thanks, Ryan
