Heard that Carroll was driving a race and pumping Nitro-glycerin because he was fearful of having a heart attack while racing...
He went with smaller, lighter cars with HP and killed the good 'ol' boys...
BTW, the Cobra I raced ran B/SP and I was going up against 350/350 Corvettes and killed them all... It was obscene... The Cobra would run low 12s and the Vettes??? High 12s and low 13s... It wasn't even fair...
