241 red ram hemi in a 64 dart 4 door

So you're putting a 1950's motor in a 1960's Valiant so you can join the Rat Rod Revolution?

Stuck in that box, eh? Have you spent much time around the early Hemi engines...especially the Dodge and DeSoto versions? These engines are made from SUPER high quality materials and are geometric masterpieces. Minor porting goes a long long way, and in dead stock form they are capable of supporting many times their intended power levels. These things laugh at blowers and nitrous. Back in the day, T/F guys would drag these engines out of the junkyard, slip a cam in, bolt their blowers and mags on, 90% in the tank, and they'd go 10,000 RPM and 200+ MPH run after run without ever pulling the pan off. Early Hemi's are AMAZING engines. Learn a bit about them before you write them off as Rat Rod material.
