One of the only two cars I ever lost to with my GTO in my street racing days was a Chevy-Healy, a 327 'vette engine with the original Rochester fuel-injection setup. I don't know what he had for gears but as my 389 with trips was giving it all it had his taillights just kept getting closer and closer together....
