anybody know it? i found a stroker kit that claims it makes 605 cubic inches with a 4.300" stroke which would put the bore at around 4.732". i've seen the 557 strokers with 4.440" bore but with just 4.900" bore spacing you get less than .2" cylinder wall thickness that seems really thin to me.

You're not going to get 605 cubes from a stock 429/460 block. .060 is usually safe, .080 over will work but I'd get it sonic checked 1st. Check PM's.
