My '68 Hemi 4-speed RR had its stock bars & springs. No problem lifting the nose on acceleration, and though I never considered it or drove it like a canyon carver, it did handle pretty decently (I have another car for that purpose). Main problem was traction: at 540 dyno'd HP, 295/50 Radial T/As on 15x8s were useless until 3rd gear. I ran 265/50 fronts on 15x8s.
A set of M&H DOTs were needed to accelerate the thing under full throttle.
