Got the engine back from machining assembled as a short block. It took forever because I only threw money at it when I had it.
Started collecting pieces for my doubler and mocking up. Going to be an np241/205 all 32 spline.
Final ratio low low will be about 170:1
The tail shaft will be gone and front of trans. To rear of doubler will be about 3 ft. I'm going to try and get equal length front and rear drive shafts. ~5 ft each

And some inspiration

On a side note... This winter sucked for snow
