Melling 355 - LS Oil Pump 25 PSI More Pressure & 33% More Volume LS1 LS2 LS3 LQ4

Why did you pick this product vs others?:Shipped quick

I put this pump in my 5.3L when I replaced my cam. I went from 20 psi @ 210° idle, to 65-70 psi @210° also at idle! And dont stick it in dry folks, you should always get it good and primed up with some, assembly lube... great pump tho, I'm very happy with it!

Machining looks very nice have not installed yet, but will be installing soon and very pleased with product and service from seller

Everything was amazing. On time and professional.

This pump is made to very high specs, it is much much better than the stock GM pump, I wont buy any other pump for my ls engines.

Cammed my truck and put new oil pump on it and makes great pressure now very happy with it

I get around 6-8 psi more oil pressure make sure u shim it correctly! C6 corvette ls2

Melling is just not the greatest anymore. Gets less oil pressure than my stock high volume at idle when it’s hot. Above 800 rpm it gets 40+ below that it can get down to 25 sure I know it won’t hurt the motor but come on my high volume never went below 42 psi at a lower idle
