Then you need to bolt on your bell housing on to the back of the motor. We use Socket Head Cap Screws (Allen bolts) because they offer a lot more clearance. If you use a normal hex bolt you will NOT be able to tighten up the bolts with a normal socket as the bell housing is formed too close to the holes. Notice how we do NOT have washers under the head of the bolts. We ALWAYS put washers under the head of all bolts, but here we are about to adjust the bell housing and they may get in the way. Some bell housings have to move a LONG way. We will install the washers when we are done dialing in the bell housing. Also, notice that we have put the weld bushing in place over the dowels in the engine block. There is about 0.030 inch clearance all the way around between the bushings and the bell housing to give us enough clearance to move things around. The idea here it to get the hole in the bell housing centered with the center of the crank.
