What?

My 69 b body which is the same car as a 70 weighs 3620 w/ better than a half tank. 440 would add only a few pounds over my 383. I have maybe 75 pounds AT THE MOST in aluminum stuff weight savings.

I also have a full spare and a jack at the 3620 weight. Power steering would add I think 46 pounds based on what others have figured on here. MA article said 90 vs. 12 so...
