I have two vehicles with a B engine installed if you cut the B flywheel shroud off it is a direct bolt in job . The shroud is used in a B car or truck to mate up to the B flywheel housing which has the same bolt pattern as the A housing . There are two different attachment styles of the shroud to the pan one is a continuous electric weld the other is spot welded . You have to cut the welded one off with a cut off wheel being careful not to cut into the pan itself . You can drill out the spot welded style and MIG up the holes . The A pan does not fit the B motor . When you bolt the A flywheel housing to the B engine be sure to fit the paper gasket or you will have a leak from the rear camshaft bearing . Use the small "C" shims at the top two bolts so the housing is square to the block all the vendors sell these. You have to check the runout the "Barn" will tell you how . This is important so the transmission is aligned correctly .Before you fit and run the engine drop the pan and pop out the dipper tray and clean out all the gunge (you will be surprised) and open the valve chest and clean that out as well .All the gaskets are available for the B engine . Check for block cracks around the valve seats USA made engines are prone for this .
