clearancing a late model block

Hi guys, we are building a 383 stroker with a late model block, one piece rear main. Looks like there isn't a lot of clearancing needed. I may be wrong but who has assembled one themselves. The rods didn't hit the pan rails nor the cylinder wall. Given we haven't checked every cylinder. The motor will have to be machined before we clearance everything. Any information will be appreciated.

We have machined out a few of those blocks for some other engine shops and builders and have found that the later blocks have a little more clearance over the earlier blocks.

We have a program in a our CNC machine to automaticly clearance for stroker rotators. On the earlier and late blocks there always seems to be a one side that needs a little more work.
