Isn't the bogging down when putting into gear due to a torque converter problem?

No. That is the oil pressure dropping to low to feed the system.

The barrel of the HPOP is made of brass.

I think I misspoke. It's goldish. I'm thinking main bearings. So probably copper not brass. Im thinking this may explain the drop in pressure in gear - i.e. crank walk.
Supposedly they machined the block with the girdle on it but im wondering if thats actually true. Or just didnt get it right. Or didnt balance the crank correctly with the .030 over pistons.

The crank and pistons are usually balanced by them selves.

Time to stop guessing and pull the motor.

That really sucks. Who built your motor? Sounds like something similar i had built only mine didn't come apart completely. Lol
