You should be able to sell some of the 800 CFI parts to offset the BB swap. Like I mentioned, the first thing I would do is connect with Brad at Power Addiction Racing for the engine plate. They run about $210 plus shipping but it is well worth it. The engine plate is the base that will dictate how everything is going to be fitted to the engine in the chassis. Brad's plate takes all the guess work out and it fits like a glove.
