[RICK LAKE]

1Trkpony Russ Drill two small holes through the bell housing and into the block. Use these as your alignment dowels. Heating, drilling, tapping, hammering, and drilling out the back side can all break that Aluminium block. Get 2 long 1/4 roll pins, drill 2 1/4 hole about 1/2 deep through bell housing and block, Tap the pins in and everything will be centered. Messing with thoses dowels is a pain in the A$$. I ground out all my mount holes to get mine centered ( bellhousing) 3 hours later from .038" to .002" in the car. Welded nuts to the bell housing to keep centered. I just did a stroker kit and rechecked the bell housing again. It was .012" off. I recenter the housing( out of the car) and added the 2 pins at 10 o clock and 2 oclock. Removed the housing and rechecked center after pins reinstalled, bell right on the number. This is alot easier if you have the room in the holes to move the bell housing around. I have each bell housing for each motor, I don't switch them. Mated for life, or explosion, which every cames last. Rick L Ps 90 degree drill make this alot easier in the car.
