The farther I get into this project, the more things I'm figuring I should replace!!

With a 69 350 block, Holley stealth ram, trick flow heads, etc., should I run a stock oil pump, or should I replace it while I have the motor out?

What one should I get? Is there anything else I would have to change??

Maybe I should just PM you instead of posting

So this one?

Stock replacement. If that's all I need, sounds good to me!

 

• Melling M55 oil pump (MEL-M55)
• Melling 55s pickup screen (MEL-55-S1)
• Melling IS-55e hardened driveshaft (MEL-IS-55E)
• Mr. Gasket #26 pressure spring (MRG-26)

That's about all the oiling system a small block chevy will need, given no added oil clearances or added flow volume.

 

Ok, cool! I'll order it up!

 

bringing this thread back. i just ordered all this stuff to put in my 350 motor that i have on the stand. will the Jegs pickup retainer (part # 555-23620) work with the M55? just wanna be sure before i order. thanks.

 

it should, pretty universal fit. i hammer a flat on a 1/4 round, drill a hole in it, weld the round end to the pick up and bolt the flat end to the pump.

 

i know this is a very old thread but would all of those items fit a 93 350 block...

 

Should bolt up fine.

 

The M55 is no longer recommended for a high performance engine. Since this thread originated Melling has reduced the casting thickness of the M55 oil pump. In a hi-po engine the casting will break off in the neck area.
