Those of you running an lsx block, what are you using for an oil pump and what rpm are you spinning your motor to?

Thanks in advance,

LS4 pump. 7000RPM when I had an LSX block.

Same pump with RHS block now.

Well guys, I can't thank you enough for holding my senses to the fire. Had I installed the HV pump, I would have had good oil pressure but only for awhile! I could have damaged the crank beyond repair, or worse, a spun bearing. So it's take awhile, but the mains and pins are at a happy 20/20 with chamfered oil holes and radiused journal ends. She's back together, fired up second try. Best of all, I have excellent oil pressure! When at full temperature, oil pressure is just below 35 psig shown on the factory gauge. That's an incredible improvement over what was doing. So thanks again! Now, does anyone want a brand-new-in-the-box Melling HV pump?
