What has your street 340 and 360 combos ran in the 1/8 & 1/4 mile?
B3422w5. I don't no. I weighed it on a nhra scale and that's what it read. Surprised the hell out of me. I weigh about 260. I'll weigh it again this spring when I go back to make sure.
IMO the total weight on the scale is about right.
Its within the range of what I've seen, even considering options including undercoating etc, fuel fill etc.
My '67 notchback was 3201 lbs (without driver) on digital scales, and around 3390 at track scales (Englishtown) with the trunk full of tools (about 150 lbs worth).

Seems to be in the same ballpark.
