Which is exactly why the SRT4 swap is ideal for the Valiant. I considered doing an SRT4 or Pentastar swap in my Duster, but only briefly because it just wouldn’t seem right having that type of exhaust note coming from a car like a Duster. Now, for my 67 Valiant? Absolutely! In fact, I considered doing a pentastar swap in it, then I decided I was going to do the SRT4 swap. However, since the primary use of the Valiant will be driver/family vehicle, I have since decided to go even farther off the rails and do a 1.9L VW ALH TDI swap.
