skewing the dyno??

I never took my best running "stone-stock" 318 2bbl to the track. It was a '72 Demon with about 39k actual miles. I did run a B-body with a 318 2bbl /auto/2.94's (i believe) and it went 15.9's @ 84 mph. My Demon was a faster car. I think 15.6's or 7's for sure.
That's funny, I had a 73 charger 400 2 bbl with I think 2.94s it ran 15.9s
And I thought my 73 340 Challenger was a sled. 9.75's figures to 15.22 in the 1/4. That 318 Demon running 15.60's isn't bad.
