mopar made a 360HP L code in 1974 with the 340 cam and valvesprings and double roller timing set and windage tray and dual exhaust. it made 5 more horse and 25 more torque than the 1973 340.View attachment 1715134376
Well if I come across one of those L codes I'll be sure to give it a look! To be fair, I believe 73 was when they made a major emissions change to the 340
