Oh dear! Misprint! Misprint! I meant 1250, not 1750.
Could I ask the question again, with all my feet out of my mouth.
When I win Lotto and decide to enlarge my engine, what are my options? I imagine the existing block can be bored out a bit, but what exactly is a 1250 engine? Is it similar externally to my little 998cc engine? Could one be lifted out and the other lowered in with little modification? In other words, has the bigger engine the same external dimensions as the smaller one? Is there a publication (printed or online) that would enlighten me?
Edit: Long-term dream.
I don't want to hoon along the highway at suicidal speeds. I would like the extra power to crawl around the bush a bit, possibly towing a little trailer.
Of course, first I have to buy the lotto ticket.
