Depends on the set-up (tire and wheel profile, shock settings, stock bellhousing or blowproof, cut or not cut,
oil pan, etc.). Figure 4.5" of clearance on average. Some here have reported a little lower, some a little higher (+/- .5 inch). Also check the front
oil cooler surround ('glass) clearance...usually about the same.
Oil cooler shroud, oil pan and transmission bellhousing will be your three lowest points of potential contact.
