Pistons should be here tomorrow,so the block will go out in a week or two.

One part down,many to go.

Not to upset but KB 251 are a 3.75 stroke piston. You will need pistons that are designed for a stroker crank. It may be in your best interest to buy a stroker rotating asembly from one of the very knowledgeable board members or Scat who have been building stroker assemblies for decades 440 source.

These pistons will sit .160 below deck,plenty of space.
Depending on head and gasket,compression will be around 8-1 to 10-1
If I could afford a complete assembly I would.

Earlier posts lead me to believe you did not have a well thought out plan. I was mistaken my apologies.

No need to apologize its kool and as far as a well thought out plan, haha not here.
