I just read te article beginning to the end, Nice review. the most exciting thing I read was that the engine has changed abit including the name. NX77 7.7 The article said the engine now has three ports thay have new porting for low torque and higher rpms!!! I would like to see if the cylinder sleeve fits the NX76 Block and crank becuase a frein of mine was telling me about cutting a special connecting rod and piston to see what that would do for rpms.. We'll see soon!!
