Just ask Mopar. Ever notice how you really don't see any Dodge Red Ram hemi's around? The 241, 270, 315, and 325 all lacked harmonic dampeners. That resulted in some pretty short crankshaft lifespans. I happen to know a gentleman that is rebuilding a 241 for his Dodge hotrod truck project. He has $15,000 (!) into this engine because parts are impossible to find. Retrofitting a harmonic balancer was of the utmost importance for him. The sad part is I still fear that little hemi will struggle to break 225 horsepower...but hey...it's period correct!
