Default Oil Pump #12555884

this part number 12555884 from the gmpp catalog lists the pump as "LT1." does anyone know if this is truly the stock LT1/4 oil pump?

either way, does anyone know if this pump has the 3/4" inlet or the earlier inlet?

thanks.

I'm not 100% certain on the size but 3/4" sounds correct. Should have the new one in my hands by this weekend and I can measure it. If my brain goes tilt and I forget, fire me an e-mail :)
