Engine Identification

[Miniac]

Can you please tel me about this motor its suposed to be a 1275E but my engine number is10H743JH3494 thanks

10H with the oil filter pointing upwards out of the engine bay is what we call an SA 1100 bigbore motor, these motors are pretty much bulletproof in their stock form as they have a compression ratio of 8:1. The SA 1100 can be converted to a 1275 with a few 1275 parts and some engineering but this can become costly, you might be lucky and find that your motor was swapped out with a 1275 and the previous owner just retained the original engine plate to save the schlep of having to do engine clearance.
