The engine rebuild is finished, the engine is back in service and nearly broken in. I've put 2,500 miles on the new engine and I think it is to the point where it can be considered reliable. I don't know what kind of power this new engine is giving me but I am very happy with it. Tires will spin easily in 1st and I can tap them in 2nd and I still have considerable power in overdrive. Mileage? With the EFI setup I am getting about 18, and that is not with a conservative right foot.
