It sounds like the big end bearing failed. You'll need a big end pin & bearing, con-rod, plus the other bits you mentioned. Its one of the most common & expensive failures to have on high revving / high compression motors. Replace the big end bearing after 6 hours running, and use a castor based oil in the fuel (I always thought Castrol R40 was best).
