EX-2143 was the 'Burke-Bros.-Leggit-Exostec' last powered by a 305 ci. destroked Chrysler Hemi built by Les Legget of So. Cal. The engine was set back and the stock upholstery was removed and replaced by one bucket seat towards the rear of the passenger compartment. In the suspension dept, the complete front suspension was removed and a straight axle put in to keep it straight at speed. 18" rear wheels were used to increase the gear ratio,while a set of small tires were used at the front to keep the nose down.
An attempt was also planned of a larger engine for the B/Fuel coupe class, but dammage to the rear frame crossmember and parachute mounting hardware when Steve Burke poped the chute at full throtle, forced the retirement of the car. (alt.autos.studebaker - Aug 2005)
