The link in the second post is a crf picco based Orion, I don't no if u missed that or maybe a bit slow on the reading but that's what I was referring to. Honestly the new CRF alpha orions engines really are becoming the premeir engine when it comes to high level racing. One thing to say is 'budget' and spending 400$ on an engine that may only be a tiny hair better then a b5 is kinda pointless so keep in your budget so u can stay at the track longer.
