Will stock engine mounts work on BBM block? Does the side oiler feature effect engine mounts? 1976 F100 is what I’m working with… thanks in advance
Original Ford 427 Side Oiler blocks have the lower drivers side motor mount bolt hole in a slightly higher position, to clear the side oil galley, compared to all other ‘65 & later FE blocks with the 4 motor mount bolt holes per side. It’s just that one hole. Cars that originally had a 427 Side Oiler option had a unique drivers side motor mount, where they bolt to the block, to match that one raised hole. Original ‘65 -‘68 427 motor mounts for those vehicles are very rare, most people now usually just do something like slot that one hole in the mount, and sometimes you will need to clearance the bottom of the drivers side mount to clear the side oil passage hump on the block. The passenger side on an original Ford 427 Side Oiler block has the same bolt hole pattern as other ‘65 & later FE blocks.
Since Ford pickups never had a factory 427 production option there was never a unique original production 427 motor mount offered, so to put a 427 Side Oiler block in a pickup will require modifying a drivers side motor mount in any case, for that one bolt hole, and possibly the side oil galley hump.
My assumption would be the BBM block has the same motor mount bolt hole arraignment as the factory Ford 427 Side Oiler block, but maybe others can confirm.
