you aren`t running the h.p. I`m talking about, but my old hemi car tore up pinion snubbers no matter how they were set, and couldn`t keep front spring clamps located right. we were running 002-003 springs and nothing else but 14 and 16' slicks. It carried the wheels to the second gear change , the few times it really hooked up. Track prep was pretty bad back then, and firestone slicks were the only ones that came close to working . -Back then.
