All,
I'm currently building up my 320 engine. Seems to be going ok so far; I have the crank and camshaft in (with bearings obviously) which are prelubed with engine building paste. Also rear main seal installed. I left a slight amount of interference on it by cutting it with a box knife blade laid flat. I noticed this rotating assembly so far takes 25ft lbs to move from a standstill, and 8 ft lbs to keep moving. Is this normal for a NEW seal, or did I leave too much interference?

You need a 2 1/2 inch diameter cylinder and I found that a 1 7/8 socket works perfectly for that. :)

To replace a piston, do I press out the old rod bushing then drop it in after heating the new piston head in water?

Unless the engine has had exceptionally long and severe use, the piston pin bushings are often reusable. This is because the Packard V8 rod is about twice as wide at the small end as is the norm for US V8s. There's much more bushing material spread over a wider area.
According to the Packard Shop Manual, a special burnishing tool is required to properly install new piston pin bushings. jack vines
