G'day Dermot
There were two different 1098cc engines.
The first ones (engine prefix 10CG in a Sprite/Midget) had the same 1.75" main bearing journals, and the same bolt pattern on the flywheel/crankshaft, as the 948cc engine. These engines were fitted to Mk II Sprites, Mk I MG Midgets, Morris Minor 1000 and Austin A40 Farina. The engines were all essentially the same except the Sprite had a different cam grind, and double valve springs. And of course twin SU carbies.
It soon became apparent that the crankshafts weren't strong enough for the increase in capacity, so the next generation of 1098cc engine (prefix 10CC) had 2" main journals and a wider spaced bolt pattern for the flywheel. These were fitted to Mk III Sprites and Mk II Midgets, but never found their way into Morris or other Austin products.
So I guess to answer your question - the Moris Minor 1098c engine will fit straight into your Sprite. But make sure you get the flywheel with it.
