I bought the block at an auction my employer held. We used it for oil testing. It ran at 3000 rpm at 250nm of torque for 600 hours. It has a bore size of 3.903" (.023" over). It has a ton of meat left in the cylinders. It is a standard deck height. The block was custom made for us by GM. The only difference between this block and a standard LSX is that all the cam bores take the #2 position cam bearing. This won't affect anything for racing. You can run any LS cam you want. The bearing part # is Durabond CHP-25-2 or add the T if you want a coated bearing. You have to call Durabond directly to get 5 of this part #. It has cam bearings installed already, they have 100 hours on them. The ARP main studs have been cycled 12 times. The screw in water plugs, windage tray nuts, and the main cap side bolts are all included. The casting number is # 19260089. The part number is # 88958771. Message me for extra pics or additional info. Price is $2295 for local pick up. Add $300 if you want it shipped in the lower 48. Thanks, Josh.
