Stock weight distribution for various body styles - can you improve balance w/out drastic mods?

That's not even close to 50/50, if you actually weigh them, there not even that good. Don't trust some magazine article.
The article was from Mechanix Illustrated from 1967. I trust them. Of course every configuration changes the weight distribution. 170 /6 with three on the tree and 7 14 rear, compared with 383, 727, 8 3/4. Obviously, the best is when you measure them.
