I read about problems with Dynoflo 3-4 years ago on this site, and it was the same complaints about thier engines failing and them (Dynosuck) not standing behind it.. One guys storie said he even drove to their shop and picked his Completey assmbled and dyno tested eng up and it still blew up on the first pass and Scott blaimed eveyone but his own co. Sad to think 4 years later they are still doing business :shock:
