modify bellhousing??

A sI mentioned in an earlier post I have SB aluminum bellhousing with a 4.3" bearing retainer hole and a transmission with a 4.8" bearing retainer.

Where I work we have access to numerous machine tools and people I work with some very talented machinists. We have looked over the bellhousing and it has plenty of material in the area of the bearing retainer center hole to allow for overboring it to the 4.8" diameter. My machinists friend feels he can bore the new within .001" off the location of the original hole.

Does it seem reasonable to go ahead and enlarge the hole ?
