Yes, John's engine was not invited back.. same true for Tony Bischoff.
John's 2015 engine is still for sale... After the contest he put a bigger cam in it, put on a Super Victor intake and 1000 cfm carb and it made over 700 horsepower.
Glad to see you got in Barry..I like the idea of sacrificing a scub on the dyno.. The LS blowups and fire added some excitement last year.
