The 948 also went in the A-H Sprite. It had 47 bhp in standard form and with the Sprite weighing less than even a Mini it was quite a 'nippy' little car in its day. I've even rallied in a 1959 Sprite,

Yes my Dads A-H Sprite should have a 948 engine in instead of the 1380 haha.
The spridgets later had a 998 or a 1098.
Our Morris Minor 1955 Split screen convertible has the 803cc engine in.
This later changed to the Minor 1000

Probably got about 5 spare a-series engines in the lock-up aswell as a b series spare

Lot of facts and figures here for the A series, although not all made it into the mini

I built an 1115 cc engine for a Mk.1 Sprite for historic motor sport. It had a 1275 engine, but that made it ineligible for some events as 1275 did not represent a 'period modification'. My old friend JohnSprinzel did build two Mk.1 'Speedwell' Sprites with the 1098 block, so that made it original. With a 276 cam, 295 head, twin H4 carbs, 10.2:1 C.R. and a better exhaust system, plus some other little tweeks, it gave 75 bhp at 5900 rpm at the flywheel.
