Although yours rhymes better, the original was no substitute for cubic inches, preceded by all else being equal.
Which, even the alleged source, Carroll Shelby knew not to be true, or so limiting as to be untrue since all else is not equal.
For the OP, gearing and a lot of low end torque can win the 0-30 sprint over sheer power. By about 60 things begin to even out, by a 1/4 mile you can almost compute horsepower by the 1/4 speed and many vehicles can start off in second and hit the same speed by that time.
See if you can find a belt driven supercharger, although the 8 speed might be able to hold up to braking to force an exhaust turbo to spool up to decent power.
Or, try nitrous injection for the rare occasions when you are next to a hemi--and sniff for the bleachy smell just in case the hemi driver doesn't like stock engines either.
