Up for sale, Melling M55A oil pump for small block chevys/LT1s
M55A's are standard volume, but with a high pressure spring (commonly known as the GM "white" spring) already installed from the factory.
It is brand new, in the box. The box was only opened to take a pic for this ad
Also, the ARP oil pump driveshaft. Part # 134-7901 brand new, unopened in the original packaging.
From Jegs, the pump is $31.99 and the shaft is $13.99. That's $45.98 before the handling charge.
Asking price: $40 shipped for both

I originally bought these for my LT1, but decided to buy an aftermarket pan and go with a HV pump instead. If I had used a stock pan, then I would have used these. You will, however, need to get the correct pickup assy for this pump, but they can easily be had from any parts store for less than $10 under melling part # 55S1
