Build thread- 73 duster, forged 5.7 w/ PS and AC, 5 spd, big brakes and floater rear

Is yours the .68 or whatever 5th? That .82 will be sweet spot heaven Wade. My 5th is .75 and even it isn't great, by the time my BB started to get on top of it in 5th I was at about the 140 mark and things start to change then....
So im with you, when I can, im gonna do a .80 5th.
