Biffle entered the first two races of the 1996 Winston West Series, finishing 30th at Tucson and 4th at Altamont. His debut in one of NASCAR's national divisions came later that year when he ran the final two Busch Series races of the season. Driving a Chevrolet for Dick Bown, he finished 23rd at Rockingham but lost an engine the following race at Homestead and finished 36th.
