LS6 oil pump?
Where can I get a ported LS6 oil pump? I'm about to start my cam swap and I'm gathering parts for the build. Should I get the LS6 pump or just replace original pump with another stock LS1 pump? Btw the car is a 98 w/ a tad over 100k miles.

I just replaced my 98 pump with the LS6 pump. I was expecting better oil pressure but it seems to be the same as the LS1 pump 60+ ps1 at 2500 rpm cold and 45+ psi 2500 rpm hot) Not sure of the exact numbers here...but it doesn't seem to be any different than the LS1 numbers....maybe its the same pump? Anyway, I've heard there was issues with the 98 pump so to be on the safe side make sure to get a post 98 pump for sure.

Oil pump
TSP (Texas Speed Products) sells ported LS6 pumps are a fair price.
Mellings and SLP also make a high pressure pump. Make sure with the Mellings that you use the regular spring and not the high pressure spring (i.e. too much pressure) .
There was a recent article in one of Chev Hi performance mags on porting pumps and pressures.

Don't waste your time or money on a LS1 - LS6 oil pump. If you are going to stay with a wet sump system, purchase the Melling high-flow oil pump - part number 10296. The Melling pump can be purchased at Summit Racing and others.
After you have purchased it, open the inlet port as shown in any of the How To web sites.
Also, seeing that you are doing a cam swap, purchase a set of Smith Brothers oil flow restricting pushrods - www.pushrods.net - so your new Melling pump gives oil flow priority to the mains and rods, and eliminate the flooding of the overhead that you have with stock or typical aftermarket pushrods.

I'm running a OEM pump from a LS4 (I think that is right). It will peg the oil pressure gauge out if I go over 2500 rpm when the oil is cold. Idle hot is always over 40. And it was only about $60-$70.
