My engine builder bought it direct from Eagle,I was wanting to go with a Scat crank,but he said there terrible with returns(not that I,d be returning it?)I guess he just gets better deals through Eagle?It wasn,t cheap!$2K.I got a really good deal on the Eddy RPM,s still in the box,from a local FABO member that wasn,t gonna use them.So there being opened up abit for better flow.:-D
