DanEC Dan the spec you are looking for is .000" Have not ever seen this. If you can get down to .003" you are good. This is top to bottom and side to side. 2 of the numbers need to be negitive. The easy way is to buy the offset dowel pins and have them install and setup the bell this way. I did it the harder way with grinding out the holes, centering the bell and welding nuts on the locators for repeat assembly and bell being centered. It took 2.5 hours to get this correct. My lakewood was .038" out. I am down to .002"-.004", close enough for me.
Best thing to do is install flywheel, setup magnetic base and dial gauge and retest your measurments then come back with the numbers and we can see what off set dowels you need to get this setup into spec. 2 numbers plus and 2 numbers neg. You know which way to move bell. Once this is done, torque bell to block and get dowels install and twist to match holes. If you have the room, drilll and tap holes for bolts or allen head screws to lock the dowel in location. You are good to go after this. Rick L.
