I wasnt there to see Andy dyno the 514 but, I race super dirt late models in the pacific northwest and run a sb2.2 alum. 415ci. that came from a very reputable engine builder from back east that claims it to have made 850hp. We installed it on the dyno that Andy uses and it made 762hp. There are alot of alum dirt late model motors built at this shop and most make 700 to 730hp in 430ci. arrangement. These motors will run with any dirt late model motors anywhere and alot of those supposedly make over 800hp dyno'd hp. Im posting this to verify what I know about this dyno and it is known locally to be stingy compared to other known ones in the area. Im not trying to the pot. Just giving my opinion of the dyno.
