that's a smokin deal, but if you took that to a builder, they'd want 200-300 to port it most likely. So, I think you'd be money ahead to buy a cub from your builder and buy the rest of the shizz off some reputable ebay stores. VIP Racing has new H129 cranks for about $400. Alot of builders probably can't even buy them for that. Then if you know what kind of pistons you need, you can get the topend kit and gaskets from the same place and save on shipping. Give your builder a box of goodies and you're off.
