Eric Larson Boss Bird FC at Norwalk 2013 burnout
Eric drives a recreation of Arnie Beswick’s ’71 Trans Am funny car, The Boss Bird. The Boss Bird is claimed to be responsible for some Arnie‘s quickest times ever  down the 1/4 mile!
 
The car’s fiberglass body was molded from one of the original “Boss Birds” with subtle aerodynamic improvements.    A rear wing was also added in the anticipation of some high speeds. The car runs updated billet aluminum Tunnel Port Ram Air V head on 80% nitro-methane!
