I have mine set upper-hole hole with no preload, in fact i have it set for the height of a nickle long way or standing on end. The shocks Rancho 9000's set on #4. Mono leafs in the rear. The front have 6cyl torsion bars and Cal-trac shocks. The tires 28 x 10.5 hoosier slicks set at 14psi the rear end has a 4.30 gear. The engine is a indy-head "360-1" 408. The trans is a 727 with the stock gearing and converter is a custom turbo action. Leave the line at 4000 with a trans brake. best time so far 1.42 60' 10.21 at 131 mph. But i run 10.25 very contestant. I beat my head against the wall for ever trying to get them faster than my SS springs. They never did get faster but they are way more consistent and the car goes straight with no dancing in higher gears.
