Hey guys everybody I ask have different opinions on oil pumps. I'm not picky but I want reliability and great pressure. I have heard some guys complain about some pumps sucking the pan dry. So he is my build. 6.0 block with ls3 internals. Basically a iron ls3. Ls3 heads and ported ls3 intake. 92mm nick williams throttle body. Kooks headers. 92mm nick williams throttle body. Stock f body oil pan. 6 speed car that's go see the track every now and then. Mostly go see street driving 3 days out the week. Thanks for the help

The bottom end consist of ls3 pistons ls3 rods and the the crankshaft is just a factory peice also but with a 24 tooth reluctor wheel.

I like the ported LS4 I got from Synergy. The HRI ported LS6 is good as well and the Katech units are solid.

If you go Melling, make sure you disassemble and clean well before using.

Yup. I used the 10296 in mine.

I have looked at them all. They all close as far as price is concerned I see. Hubbard racing sells the the ported ls6 for 139 shipped but never seen no one on here with a response on the their oil pumps. Melling pumps sell for 115-150 depending on who you buy it from. Jake how much is the ls4 pump ? Guys running the 10296 melling are yall running the factory oil pan ( f body) ?

It was 169? Cleared a double roller without issue.

Thanks for the response Jake. I forgot to mention I already have purchased a single roller timing chain from cloyes.

I bought the LS6 pump kit p/n 17801830 for $75 plus free shipping.

I ported it myself with a Dremel tool in less than 35 minutes using the pdf instructions from this site, and added a shim in the pressure relief valve to increase system pressure using the same pdf instructions. I spent about another 30 minutes cleaning it when I was done porting and about 5 minutes re-assembling it. Having done the first with the Dremel, I could do the second in about half the time (maybe 15-20 minutes).

Porting it DIY is not nearly as complicated as some believe it to be, nor does it require the uber tools.

I never seen a ls6 pump for the cheap shipped.

I have the high volume std pressure pump in my 402 LS2. This way when I add my oil cooler I won't have oil pump volume issues.

Baconz28

I have did business with hubbard racing on some gaskets etc....
. Great customer service I must say. I just never seen no one say how oil pressure is on their oil pumps. What a 402 ls2 I'm sure oil needs is probably different since you do have a stroker crankshaft in the motor.

I hear everyone running the schumanns love them?

Baconz28

I just went to they website. They stuff looks really nice but I notice all their pumps seem to have "extra volume" and no prices on their site neither.

I bought it from Jegs, but apparently the price went up since I bought it.

Baconz28

Everybody i talk speak to have a different response on the melling pumps so I'm kinda thinking they are a hit or miss deal. I want to do it right the first time and be done with it so I'm still open on opinions......

I have the melling m295 pump, which I'm pretty sure is a stock replacement and its been fine. I have a good amount of pressure at idle and cruising when fully warmed up.

On my 346 Im getting 40-45 idle, 45-50 cruising, and WOT is 70-75. Buddy of mine is about to put on in his GTO in a week or so but its also a 346 so im guessing around the same numbers

Stock volume, high pressure. Melling 10295

Melling m295 the stock replacement is also fine.

You can get it right at advance auto parts for about $75 after coupon codes. The 10295 runs around $50 more but you have to pay shipping on that.

Do horsepower level matters when choosing a oil pump ? I see similar combos I'm building push out an estimate of 550 hp at the crank. High 400s to the tire.
