is there any different kind of oil pump besides the stock one that makes any difference when there is not a supercharger or a turbo on a engine that has just a cam, p/p heads , and boltons. i am rebuilding my engine that has 89k on it and im going ahead and putting a new oil pump for future safety

 

im pretty sure all you can get is either stock or modified-stock oilpumps
ive never seen anything else

 

I've been running an LS6 ported oil pump for 15,000 miles so far, and I haven't had a problem.

 

Does the LS-6 pump run at a higher PSI?

 

check with AP Engineering----->
Might still be able to get in on the GP they had going

 

There are just stock and modified stock oil pumps. I got a ported LS6 pump from TSP and its great. Get's up to a healthy 80 psi at WOT. I don't think there is much of a difference between the ported LS6 pumps. There is the TSP, Katech, SLP, and one other. I just bought the cheapest.

 

Melling is making a new designed cast iron front case oil pump.
Haven't heard much about them though, they claim higher volume then stockers.

 

Hmm that should be interesting.

 

You can always go dry sump, which is what I am going to do if I have anymore o-ring related problems!
