Rotax 440 questions

Hey guys just bought a older 92 mach 1 with a project engine currently installed. I know it has been ported and polished, and has some of the biggest carbs I've ever seen. The block tag says its a 440, but the jugs are massive. Are there any jugs that would fit this sled other than the stock 440 jugs? I own a mxz 583 with some pipes and it feels like a kitty cat compared to this. Does anyone have any ideas on how to find out what size the jugs are? It looks like a older 440 block that's been cleaned up. Any help would be awesome.


Thanks
