need a donor engine

[maggott84]

hi every one i recently brought a zxr400 from ebay as a project but have found abit of a problem! the cylinder block has not 1 or 2 but 3 quite big cracks. i dont think it is really worth trying to get it repaired. so i was thinking maybe try and fined a engine with a dodgy box or bottom end and use the top end. iv looked at second hand engines but havnt got £400 to buy one lol. so if any body has a engine with a dodgy box or bottom end that they would be interested in selling please let me know cheers
