Oil Pump Change Debate
Is it worth changing the oil pump out on a low mileage truck during my cam swap and Radix addition?
I've been told to not use the high volume oil pumps.
Are there better oil pumps than the stock one that's not a high volume type?
If you guys think the stock pump will be fine, then I will not replace it.

I say it will be fine. Some say to replace it for peace of mind, since you're in there already. I ran the stock pump in my 5.3 till I removed it at 118K miles, motor was Radix'ed since 35K and cammed since 88K. No issues at all.
I have heard that high volume pumps run the risk of sucking the pan dry, and that high pressure ones are not needed except as a band-aid for some other problem.
If you are going to replace it, I'd recommend something like a Melling performance stock replacement.....Summit has them for a decent price.

Is there a recommended engine size or specific HP range that a hi-volume pump is needed?
What about the high pressure pumps? When are they needed?
What are the major differences between the two?
I was hoping someone had a recommended oil pump that is of higher quality components and blueprinted.

I think I will just keep the stock pump. I haven't really seen the answer I was looking for to go with another pump.
Unless someone else has more info to share in this department?

man theres nothing wrong with a stock pump. if anything you just port them to remove some of the restrictions the stock one has. next alternative is a LS6 pump and then a ported LS6 one. you dont need no other type of pump. its just a waste not to use a stock pump or ported one. ive torn the pumps apart enough to know tha hte only thing in them that can fail is the spring and thats not likely with a decent mileage motor. now if you had sludge then i would worry
