340 4 barrel and 340 6 barrel: were they really UNDERrated?

Waaaay back in the late 70's, I was racing my Chevelle every Friday night at the old Heidleberg track, not 20 miles away. One of "our gang" was a couple years older than us and more experienced. He ran a red 70 Duster bone stock, other than headers and a "shift kit". I don't remember what rear gears, but I know he ran L60 bias ply cheapo tires on the back.

That car was so consistent it was ridiculous, and it ran 14 teens. Every Friday night, pass after pass.

And get this: He always ran with his spare and jack in the trunk. I should add RIP Nick. Loved that guy.
