My all time favorite car was my 70 RR 440-6 which I bought with about 35K on the clock from a friend--to this day, about ? 71 or 72. The six pack setup was in the trunk, had Cyclone headers and "steel packs" with side exit exhaust, Ed and Holley 800 DP. 3.54 Dana, 4 speed, added "hang on" AC which worked great. If I could afford it I'd have one now---at least one.
I was stationed at NAS Miramar, San Diego (Navy electronics tech RADAR) and lived through the gas crunch and the double nickel. Got stopped twice down there in a CHP roadblock "emissions." Hell there's probly still a warrant down there for me
