Re: Oil Pump - 383 supercharged
I saw this yesterday and noticed right after your post it gives suggestions of other posts. Since no one has responded I suggest you check those out. I checked the 1st one and it had great info.

Re: Oil Pump - 383 supercharged
Will you be running an oil cooler? Things like oil coolers call for “high pressure” oil pumps, to compensate for the drop in pressure that stems from the added plumbing.
When you build the 383, are you adding anything fancy? Piston squirters? Aftermarket block with priority main oiling? Such additional branches in oil path call for “high volume” pumps.
What are your plans for the car? Street/strip? HPDE?
Longer run times at max performance (like HPDE and other road course events) also call for “high volume” pumps, to keep things moving and maximize opportunity to dissipate heat. In these cases I’d also suggest that oil cooler.
You can generally get pumps in HV, HP, both, or neither.
Melling is a longtime builder of oil pumps for high performance engines, and they have a solid selection for LT engines. Go to their website, enter your year/make/model/engine, and pick the one that seems right to you.
Many of their pumps come with three pressure springs so that you can swap them out to increase or decrease pressure. That means you only have to choose the volume when you buy.

Their site has this one (10554ST), which looks like it has the higher pressure spring installed, but it doesn't seem to be different from their M155 as far as construction goes. The M155 and a spring would be about half the price of the 10554ST. The 10554 looks like it has the chromemoly shaft and steel sleeve. This one seems like the move.

Don't forget to replace the stock plastic shaft housing/retainer. Seems like the replacements are getting very expensive:

Make sure the material of the oil pump driven gear is compatible with the cam manufacturer's recommendation.
Tick also sells only the Melling 155 pump. When we built my stroker (20 years ago) the engine builder, who had extensive experience on 1,000+ HP LT1's recommended a new GM standard volume pump, with the 80 PSI spring (engine has a redline in excess of 7,000 RPM). Engine used stock oil pan and windage tray. They "blueprinted" the pump based on their experience, to prevent cavitation and improve flow at high RPM.
