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

It’s surprising that the 67 would have better weight distribution. I always assumed that one benefit of that glorious rear glass on the ‘66 would be that it sits over the drive wheels.
When I drop Demon off the rack I will use my race scales and get corner weight for each. I had not even thought about it as I was building a daily driver. It is clearly not stock tho. 6.1 Gen three with Hemi Denny K frame battery in trunk alum radiator etc. great question and got me thinking (no small feat)!
