HI Hewey,
You could put all that piston slap and
oil burn s*#@ behind you and put in a ford engine!!
Seriously, do what you can afford. I would only say that while it is out of the car it is easier to do these things.
If the bore is out of round I would get the block machined and fit new bearings, oversized pistons and rings etc.
I have mikes bore gauge here, I would ask Mike if you can borrow it and I will get it to you.
I have finished my motor and hopefully put in in this week end. I have some pics in my gallery.
