Moparman73, great looking Dart Swinger, 70 I believe, really looks good in the blue color. You've also upped the performance value of your 225, that really makes for an interesting combination. I too increased the efficiency and maybe gained some HP along the way with mine. I added the Super Six and a 2bbl carter from a 318 with open element K&N to breathe a little easier. Mopar elect. Ign., orange box, Accel coil. Hooker Headers 3 into 1, real dual 2.25" alum. Exhaust w/ H pipe crossover. 2 glasspacks, chrome tips out the back. Auto.(904), B&M Shift Improver, and Quicksilver shifter. In the back an 8 3/4, 742 case, 3.23 gear set. It all works, I'm happy with car and engine choice.
