Just to be complete, here is a breakdown of common displacement "upgrades" for 3.0L motors over the years:
3.0L - stock of course (95mm bore x 70.4mm stroke)
3.2L - 98mm bore x 70.4mm stroke (no case machining required) AKA short-stroke
3.3L - 100mm bore x 70.4mm stroke (case opened to 105mm)
3.4L - 98mm bore x 74.4mm stroke (no case machining but also need 3.2L Carrera crank & rods)
3.5L - 100mm bore x 74.4mm stroke (case opened to 105mm and need 3.2L Carrera crank & rods)
3.6L - 100mm bore x 76.4mm stroke (case opened to 105mm, pistons need addl. machining, 964 crank w/ 3.2L Carrera rods)
3.7L - see my first post
Hope this helps.
