Plan on changing my 100k mile pump when I have it apart for cam swap.
I've read the threads on the new design Melling pumps which have been breaking and Melling recommends their "select" pumps for high performance applications.

So I'm thinking of getting the select Melling 10554 pump (std vol/std pressure)
Getting the GM white spring 3848911 to put in it for higher pressure
And then getting a new GM pickup tube, 12550042

Will all of those parts work together and is that a good proven combo?

 

Yep, that will work. Most people tac weld the pickup on as well, just for added insurance.

 

just out of curiousity, how come nobody buys the stock pump? discontinued or price prohibitive?

 

I am running the Melling select 10554 w/ the GM white spring. I have 30-40 PSI at idle and 60-70 PSI at WOT. I brazed the stock pickup on tight.
Great combo in my HP.

 

Melling redesigned it supposedly at the request of GM, it has much thinner supports and it not recommended for higher performance motors, people have been breaking them due to motor vibration.
Here's a pic I found comparing the stocker M55 to the "Select" pumps

 

Great thanks, I will tack weld the tube on as well.

 

what are the differences in the Melling select 10554, the M55, and the M155???
I already have a M155 can i use this and just use the M155 instead of the 10554 with the same components as listed?

 

Look at the pic posted above.

 

i have very good oil pressure with just the white spring - at 650 RPM hot its just under 20. Driving around it stays between 35 and 50, and WOT hits 60. cold motor will hit 70 sometimes.

I wish i would have known about welding the pickup tube while i was in there though...

 

soory, i did see the picture, i should have been a little more specific to what I am doin,

Ok, well as of right now I am building a "temporary" engine for my car it will be basically stock other than a a CC306 and car has bolt-ons in sig, my new engine should be ready next spring(budget permitting), and I am pretty much just doing new rings, rod b., main b., cam bushings and I already have a M155, instead of spending the $8X.XX on the select can i safely use the M155 with new white spring and new tacked on pickup?

I know the 10554's casting is stronger, but I am doing this rebuild on a shoe string budget as to not take away from funding from my other build and I need a dependable motor in the car right now since it is my daily driver...
... and thanks for all the help in advance and for all ya'll have helped with already!

 

sounds like your all set. as long as your going with std vlm and pressure you should be good to go

 

You'll be ok.
