Things are so dead on the list I figured I'd bore you all with my engine project.
Today I finally mailed my crankcase and crankshaft to Rick Davis to have him rework both to his specs. He will also be mounting a 2.62 to 1 E gearbox to my bottom end and sending me a side mount 618 style exhaust.
My cylinders are still at my local machine shop as they had to be bored .020 over. Been a little longer wait than I hoped, but hey, my bottom end won't be done for a couple weeks anyway. I still have to order new jets for my Bing 54's as they were jetted for the 2SI engine. I won't be working out my radiator plan till the engine is assembled. Will also need two carb boots from JBM in Ohio.
My youngest son Joshua has taken the offset motor mount plate drawing "Richard Girard so graciously provided me" to his Vo-tech machinist class and will be CNC cutting it next week. It's gonna be sweet.
All in all I'm getting close to a sweet assembly project that should end in a very potent power plant that will not add much weight to my bird with the addition of 20 hp. We shall see.
