Got the big thing apart!

Can't get the stupid time cover off cuz the balancer is on there!

Had to buy bolts and washers, the one doesn't turn over. Dumped some atf on the pistons, one is good, the other two aren't. Gonna try the other bank soon.

Try some Marvel Mystery oil or penetrating oil, let it soak real good. I had a 478 that got exposed to the elements and finally freed it up but one piston ended up getting destroyed because there was just too much rust in the cylinder wall.

Got one loose, I think the other is loosening. The other 4 aren't budging so I'll probably bang em out once the crank is free.
