To Mopar Virgin and 66fs, the exhaust changes are as mentioned. The engine, a 225 is basically stock configuration but I did add the late 70’s Super Six mods with Carter BBD 2 bbl an open element K&N air filter. Mopar elect. ign. with orange box, high output Accel coil. No other major internal changes. MPG’s anywhere from 18-23 on 87 at pump.
