For those seeking info on Block Clearancing for Stroker Crank's be it for a 355 or 383 here is a little vid I came across.
Having done this myself its a pretty good indication of what needs to be done despite being a ls7 not a 304/308.

The crank and c/r will determine how much metal needs to be removed, some require more than others. I run a scat crank and A9l rods.
Beer gut you may have a Vs block that has factory clearancing for a stroker crank as posted above?
