Even the Alfa 2600 from the fifties was a delight...
Bore 83mm (3.27") Stroke 79.6mm (3.13")
2584cc 8.5:1 compression, 130bhp @ 5900rpm, 139ft lbs torque @ 4000rpm
Alloy block and head, twin overhead cams, slightly oversquare and a bit revvy, it must have had some performance potential.
The 2300 might well have derived, though, from this little gem from 1928:
62mm (2.44") x 82mm (3.23") for a capacity of 1487cc. With a single Zenith carburettor it gave 54bhp @ 4500rpm, it had an iron block. Clearly this is the one that grew to be the famed 1750 of the early thirties, but was it stretched to 2300cc?
There was a series of drawings of this sort of thing published in Australian Motor Sports in the late forties and early fifties, I'm sure one of these engines was depicted in this series... must find it.
