M55 is not the casting number damn it , its the part number the casting number is else were on the pump... M55 is the typical PART # for small block Chevy's and 4.3l V6s... that one should work fine...its an M-55 High Volume pump. I've sold a few of them in my time at advance auto...actually they have both the M55 and M55HV IN STOCK
