You can get an older block (893) and go out to a 1030 (75mm bore) but it wouldn't last a week riding on the street. For what you're wanting, either a 945 or a 970 would serve you well riding on street. Bear in mind you'll have to pay extra to get cylinders replated (one reason I like the 893 blocks). Hope that helps.

I think the Blackbird engine is an option.
Not sure what's involved in fitting it though.

That's my next project Bladeracer. I've gotten some information from a guy over at psychobike.com to get started with. It involves drilling out rear mount holes in frame to accept larger Blackbird bolt. Then installing rear of engine and rotating it up towards frame. Then something about cutting off front mounts and rotating them or something. He didn't give me the full story but he said it wasn't that difficult. I got a buddy with empty XX case and head. Soon as he gets done with his turbo Bird we are gonna see what we can do. I have a spare RR frame so that really helps. And since he is going turbo he won't need those 41 FCR's, erion cams, and erion exhaust:eyebrows:

That has GOT to be sarcasm, cause you know it isn't going to be any fun. What WILL be fun is launching 80+ ftlbs. of torque in a 900RR frame:smilebig: Not to mention no more spun #3 rod bearings.

No personal experience with that kit, but it's just 2mm over. My 945 was 2mil over and back when I bracket raced it, I sometimes had to run it back to back several passes in a row with no overheating problems. Did he do anything else to the motor? (cams, head, etc.?) Definitely need to get a set of flatslides so you can let that monster breathe.
