The crank is on its way back to Moldex, to be repaired enough to use cylinders 1&4 as a twin. The hemi head is at the welding shop awaiting TIG closure of gaping holes in the water jacket. I wasted some time messing with the non-working thermostat, before realizing it really isn't needed- I can simply leave the electric pump off during warmup. I wanted to relocate the temperature gauge sensor, but it was mechanical and the tube was too short. So I bought a new electric temp gauge- much more flexibility of sensor location.
