          its a 511 casting. yes 3 freeze plugs.

          Mortec says its a 400SBC 4 bolt mains (NOTE: some replacement motors have 2 bolt mains)

          I pulled the pan, shes a two bolt main! Guess she was a replacement warranty motor. Good thing too I heard the 2 bolts have thicker main webs. cool!

          Cya headed to berger.

            Just get splayed main caps put on it, they're stronger than factory 4 bolts anyway, and if the webbing is thicker it will be that much better.

                            Yeah. I knew he had it last summer and I wanted to swap it in over last winter but couldnt cough up the money for it. I ended up just buying it though so at least I have it. Theyre not getting any easier to find and they go for a pretty penny in good condition, I guess this one must be kinda rare being a 2 bolt 511 casting. He wanted $300 for the whole motor which I thought was a steal. Then once I pulled the heads he wanted them (dunno why 400sbc heads suck) and said hed let me have it for $200 if he could keep the heads. Well hell yeah... more then I could have gotten outta them for scrap anyways!

                            So im pretty happy with the deal I got.

                              the heads arnt to bad the 882 and 883's are alright the flow nice they just need better valves but are really bad at cracking... specially the 883's still thats a steal for a bottom end im looking at about 300-500 for a stock bottom end but i dont know id like to make a large stroke one and the world blocks seem to be better suited for it... specailly if i want to go anything 4.0 stroke or larger almost have to do an aftermarket block.. my butty has a 2 bolt just needs a hone and bore job on it but the crank is junk and the stock pistons and rods arnt that great... so for 300 bucks not sure i want to do that much work to it...
