What has your street 340 and 360 combos ran in the 1/8 & 1/4 mile?

I looked up the curb weight on a 69 340 dart auto
3108 pounds
1970 340 Duster.... 3110
Interesting.
Similar but also slightly different than what was reported to AMA for 1970.

Could be a different definition. Full load of fuel or such could make the difference.huh-gif.gif
Shipping weights for '69 Darts here

and although its a different platform, '65 has a both curb and shipping weights on the same sheet.
