| The 4.6L and 5.0L bellhousing locating dowels are in the same place, which makes the job much easier. However, the 4.6L dowels are 16 mm OD and hollow so a bolt can be installed through them, whereas the 5.0L dowels are smaller OD and solid. All that needs to be done to the safety bellhousing is drilling out the dowel holes to 16 mm (or 41/64 inch seems to work well). The stock 4.6L dowels need to be shortened since the steel bellhousing flange is thinner than the aluminum mounting flange on the T-45 transmission. NOTE: The enlarging of the locating dowel holes is the ONLY modification to the safety bellhousing, so its NHRA approval should not be affected. |

bellhousing bolt holes are common between the 4.6L and 5.0L engines. This
includes the top two up near the intake manifold and the one on the driver's
side just below the locating dowel.{See Figures 1 and 2}
Even though only 3 bolt holes are common, the 4.6L uses bolts at the hollow dowel locations, so you end up with a total of 5 bolts holding the bellhousing to the block. This should be robust enough for almost any amount of torque the engine can be capable of ever producing. {See Figures 1 - 4} |
