You should take some pics of your frt suspension and steering setup. Usually the recommendation is to use a sag box with around 4 1/4 turns. Downey has been suggesting 3 1/2 turns.
8 turns? I need to see a video.
@knuckle47, I'd be curious what your caster angle is and what the supension setup is 1st b4 any major changes. I run a scout box which is similar to sag box. It's light but not squirrelly. It does have something like 4 1/2 turns.
Are you running atf or...
You might consider finding an rpm calculator, to see what rpms at a speed in comparison with gear ratios, tire diameters and od gearing and 1:1 outputs.
