Hey, just looking for some opinions from someone who's already done it. I'm swapping out my'48 216 for '59 261. I am either going to get a shortened water pump, or an adapter plate and keep the 216 style pump. Anyone have any problems with either? Also what do you suppose the odds of my 216 bellhousing bolting on to the the 261 are, I'm thinking they should be the same pattern.
