A WQ HO block is for sale in MN, It has the driver rear water plug issues. The 6x6 area is sticking out about 1/4 of an inch and has 3 cracks, one north, 1 west and 1 east, each 3 inches in lenght, from water plug. If someone knows a machinist who could fix it, rare block to fix. But will cost money do to rust issues. Guy said his machinist could fix it for $1000 for plug area. Then, may need 8 sleeves. Very rusty block and heads attached cause can't get loose. No intake, rusty holey oil pan smashed. Complete motor no intake. $ 350. I passed after driving 6 hours. Hopefully, someone can save it. The rear axle for sale wasn't a 390, so you didn't miss out. Good luck.
