1972 318 street build

Okay I'm putting together a virtual engine for now to get a rough price to build up to, so one of the thing I want is bore and stroke i think I'm only go .020 or .030 over with these pistons
Clevite MAHLE 2242007020: Piston 1968-2001 Small Block Chrysler V8 318ci (5.2L) with 3.93" Bore (+.020") | JEGS
or the identical ones that are .030. As for the stroke I'm not sure yet but I'm wanting a new crank because I don't want to get my original one machined down, so I need some suggesting and preferences for a crank. So that dos pistons and crank, what do we need to make those work together? Exactly I need connecting rods that will work with those pistons and crank which again I need some suggestions and preferences on those and also I would like why you prefer them to others. last but not least I haven't done many cams so I want to know you guys opinions and experiences with every cam you have had any personal experience with, not just hear say but actual experience.
Thanks in advance guys,
Thomas
