Good idea to check which one you have. Melling makes most the pumps out there for everyone else.

I read this on another site,the guy who made the original post was breaking the pumps,because the car was tire shaking so bad that the vibrations where going there the solid motor mounts to the weakest link,the oil pump,the pumps still work's and for a street car are fine don't jump to consulsion,sounds to me if the guy would learn to set the car up it wouldn't tire shake.


Some how I don't see where GM cares what a aftermarket reman supplier does with there parts,when GN hasn't used a SBC motor in 6yrs.

Anyway make your own choice's but take in to consideration the problem the gy was have causing a oil pump to break,that is some serious tire shake.

There have been several failures not attributed to tire shake. Why would anyone run the weaker pump casting when you can get one that won't fail for a few dollars more.

For what its worth, those still on a budget can run a stock big block pump for about the same money as the original 55 series. It will provide a little more pressure and volume for about the same money. I think the part number on it is M77. You just have to run a big block pickup tube which I believe are 3/4 o.d.

I would like to know what someone is doing to a motor to break the oil pump casting.


Anyway you want to be using the new 1055X part # pumps,there the Melling performance series of pumps from those that don't know.10552 is the most popular.

dirt circle track racing comes to mind, with rough tracks, and the occasional wreck, that could put a serious jolt to the oil pump. I haven't had one break yet, but you can bet that the oil pan wil be coming off of all our motors to check the wich oil pump we have. It doesn't take long to destroy alot of parts at 8000rpm's for 3/8 to 1/2 mile track.
