Re: oil pump

depends on the application and what you want to put it in..Are you racing? Are you replacing the stock unit?
Kenne Belle offers a standard Federal Mogul pump that is a replacement for the stock unit which is a known upgrade, as far as it being the best you would have to talk to a supplier like Mike at www.raceprovenmotors.com or most likley any other vendor on the site HTH

I have a Melling M55A (high volume) with welded pickup tube on my build; not a wild build by any means, but a nice upgrade from stock stuff.

FYI, the M55A is the "Z28" pump which is a stock volume pump with a stiffer bypass spring. None the less its a good pump and I use em all the time with no probs.

Dear VermontTy,

This is not directed at you.

Let it be known to all that high volume oil pumps "can" kill an engine with a stock capacity oil pan. If you scream the engine with cold oil (someone does it) you can pump ALL of the oil up top faster than it can get back to the pick-up. Then you have 5000rpm and no oil pressure. KABLEWEY!!!! (sp?)

Just something to think about,

Robert :tup:

Re: oil pump

I hear what you're saying; it's a common "complaint" that you can suck the pan dry in small block world. That being said, I run synthetic, and it will be a summertime truck only. No cold, sludgy dry starts like we get mid-winter at -30. I do not go WOT until things have been at operating temperature for quite a while, and really don't think it will be an issue for me, but do completely agree with what you're saying. If some chutney got in on a freezing day and bounced it off the limiter a few times, I could definitely see trouble. I've actually never heard of anyone smoking a motor here because their pump sucked the pan dry. If anyone has, I'd like to know your story; pump, how it happened, etc. I do know that most of our fastest members run custom fabbed pans that hold about 30 gallons, but for me, and for what I'm going to use my truck for, I cannot come close to justifying RPM's $625 price tag on another pan. Well done bringing up a very important point though......

Thanks for the input. It is a calif. truck that is just slightly modded. It will be mostly a dailey driver till it breaks again.

Re: oil pump

There are 2 oil pumps in this conversation and they are diffferent.

the Melling Hi Press MEL-55A is standard vol high pressure
the Melling Hi Vol MEL-M55HV is high vol std pressure

I agree an HV pump can starve, but the 55A pump pumps at the same volume jsut higher pressure.

Just doin research for my own build and found this thread.

Re: oil pump

Whatever you do - don't use the big block chevy pump - NAPA had a upgrade listed in their book, so I tried it out - too much pressure against the distributor gear wore out the gear. I have a mv55 now - seems to work great for me.
