Cylinder wall thickness

I am starting my 470" low deck stroker. It will be a street/strip engine that will be abused relentlessly. I will be ordering a muscle motors kit. Final bore will be 4.375. I have a block at the machine shop. I pressure washed and dried it prior to delivery. I am having them sonic check the bores first so that if its not a good block I can abort without too much money spent.

What would be a good wall thickness? What thickness would you not be comfortable with? They are checking all bores. Top bottom and middle on all 4 sides. They will give me a printout of results.

I am looking to build an eddy victor headed, solid roller cam, pump gas engine in the 550-600 hp range and all in by 6000 rpm. I want it to last. I will be using stick main caps with studs. New rotating assembly will be 2300g bob weight so it should rev quick and be easy on parts so long as rpm stays in check.
