I will take a few more picks tonight. The oil pump is shot due to air in the oil, no balance issues as its driven from the timing belt.
The Rod bearings just look worn from having a heavy crower rod spinning to 10,000rpm(logs show between shifts the motor would free rev to 10,000rpm).
They are Wiseco pistons, but I think my cracking issues is from the block moving around as much as it did. Ok I was miss understanding where they were known to crack, but I have the same issue as this thread.

All 4 pistons are cracked where the skirt blends into the wrist pin boss, only on the front side of the piston as they sit in the car. I think my piston to wall is somewhere around .005, I will check tonight.
I am thinking of fabricating an oil pan, making a crank scrapper and windage tray.
And I will be filling most of the water jacket with hard block, as a 4g63 sits there is 5" of un supported cylinder wall to flap in the breeze. So I am thinking of filling all but 2 1/2" or so with hard block to keep things straight and less cracked.
As of now I am looking into switching to CP pistons and have looked at aluminum rods. That would come down to if I can sell the Crower rods I have now.
