According to the Class Racer Info site, the 2 engines have different heads.

The 265hp engine is allowed 90cc heads. The 290hp engine is allowed 68cc heads. That's a lot of compression difference. Also, the 290hp engine is allowed a cam with more intake lift. Not sure how much power difference those 2 items would make. Would the difference be 25hp ?
Anybody have an educated guess ?
