there are no marks in the casting or any where else

948 engine would be marked '950' on the side of the block (near the fuel pump mounting hole). Take the rocker cover off - what casting number shows on the head ? If 12G202 then it's a 1098 head - and therefore 'likely' to be a 1098 engine ! There are other clues - but best bet is to lift the head - and measure the bores!

803 has bypass oil filter. 948 has metal oil filler cap. 1098 has plastic filler cap although these could of course have been changed.
Tappet chest cover centres slope outwards on the 803 and 948 and inwards on the 1098. The 1275 doesn't have covers.

Well - these 1098 engines seem to be fetching good money at the moment - so don't scrap it!
