Clearance for a 340 Stroker Conversion

340inabbody said

I see said the blind man….but isn’t that part “in-line” of the rotating assembly? As opposed to offset meaning how would that touch the crank??

As said, it's not touching the crank. It hits (possibly, depending on parts used) the block, usually at the bottom of the cylinders.

Arrows are the points of interference, circle is the clearancing needed.
Other points that may need attention:
Piston skirts (to clear the crank throws)
Oil pump housing
Windage tray
Any other points of conflict found during trial assembly.
