I found my  ’74 Challenger Rallye in La Plata, MD  in 1995 , it was originally Sherwood green with black interior.  It is presently Red Mica with black interior.  I drove it for about a year then replaced the 360 with a 440 just to have some fun.  Motor sports Ross Forged pistons, a Hughes 238/244 dur, .536/.540” hyd cam, Edelbrock aluminum heads, RPM intake, TTI headers.  Other upgrades were Firm Feel stage 2 steering box, .96” torsion bars, 1 1/8” sway bar, hemi leaf springs, added a ’70 –’71 style gas cap, T/A rear spoiler, 17” American Racing TTO’s, Kumho tires, larger front discs.
