What are you guys whining about? Take a look at how many slant six powered Mopars are at the track. Usually just me.
I also take exception to the statement it costs more to build a Mopar. My 66 Valiant 225 slant six, only cost $1500 to build, including buying the car. Do the work yourself, and shop the bargains. The car 60 ft's at 1.78, and 1/4 mile 13.6's at about 94 mph.
I have been to Lakeland, Bradenton, Moroso, Sunshine, Gainesville, Jax, in Florida, with my Valiant or Cuda, when I can afford to go. It costs me more to race, then build the cars. I mostly travel to Mopar meets in different parts of the eastern U.S. Sometimes over 1600 miles round trip, to compete in the "Slant six" racing series.
