Interesting! I'm confident that during the production run there was no variation in the Big Seven mounting plates which bolt on to each end of the block. Maybe the pre-war A8 matches the Big Seven as regards mounting, and I had a post war one that was different. I'm pretty sure the holes to take the bell housing bolts for the Big Seven gearbox had different centres from those on the A8 box - hence the transfer of gearbox - as well as the need to also transfer the clutch and driven plate. The front end definitely needed the old plate to be transferred in order to mate with the rubber mountings.
So............ anyone know more about Austin Eights???? I suggest Jacob gets some pictures before buying any (otherwise unseen) A8 engine - and he needs to buy the clutch and gearbox as well.
