351W race block question
Isn't the E3 (ZM) (A351)part numbers usually mean that its a SVO block. I think its a Sportsman block that has non-siamese cylinders, 434ci capacity, wet or dry sump, accepts hyd roller tappets, can be overbored more if sonic checked, two bolt main bearings, 3.000" main bearings but 2.749" size kit can be used with spacer kit, 9.5" deck height but can be milled down to 9.2", one piece rear main seal, and this block is made from a specially formulated cast iron also used in NASCAR/Winston Cup blocks for improved hardness, strength, and dimensional stability. This material offers excellent piston ring sealing. Main bearing webs offer enough material for the installation of four-bolt main caps. Support ribs exist at each engine mount. Thick pan rails are employed for reinforcement.
I'm not totally sure that this is the block that you have, but I'm guessing that it is.
