Your little cobra would outrun any Harley D, even that wicked freak with the V8, and most rice burners too in a quarter- even in a 8th more than likely!
I used to run my SWINGER (Wasn't stock) for ET's at Green Valley and sometimes they would put me up against the drag bikes! Yes, They made me out to look slow!
A Flat 12 was best I ever ran- BUT EVEN THAT WAS A BIT SCARY and seemed fast to me. And of course my street tires smoked half the way, and I'm sure that slowed down my ET.
My best friend bought a new SS 396 NOVA in 69, and we had lots of fun in that thing. It was sharp looking with that cowl induction and hood stripes. It was White with Black Stripes on the hood.
It definitely would pull the Roadrunners, Chargers, and even most Cuda's by several car lengths!
