Time is of the essence so I have to source locally Takes 2 weeks + from the US - overnight in Oz.

Ron Byrd has them listed on his site also racecraft bearings

Tim follow the instructions that come with the boat to the letter. Use a 1440 cut back and pitched (Mark ANderson did mine) and tune the CG per the instructions when the boat is right it will run flater than any other tunnel you have seen and will take corners at full tilt boogy without having to be set.

Thanks Eric,

Got a few mod 1440's to try on it.

Nice engine. Has a nickel plated sleeve though. If you are careful not to get it too hot and don't grind on the sleeve it will be fine.
