Yep, the hood in 70, 71, 72 was called R/T hood........the same hood 73 & 74 called ralleye hood.
The performance model was the
R/T (Road/Track), with a 383 CID Magnum V8, rated at 335 bhp (249.8 kW); 300 bhp (223.7 kW) for 1971, due to a drop in compression. The standard transmission was a 3-speed manual. Optional R/T engines were the 375 bhp (279.6 kW) 440 cu in (7.2 L) Magnum, the 390 bhp (290.8 kW) 440 CID Six-Pack and the 425 bhp (316.9 kW) 426 cu in (7.0 L) Hemi. The R/T was available in either the hardtop or convertible. For 1970 only, base hardtop and R/T hardtop models could be ordered with the more luxurious SE specification, which included leather seats, a vinyl roof, a smaller 'formal' rear window, and an overhead interior console that contained three warning lights (door ajar, low fuel, and seatbelts).[SUP]
[10][/SUP] The Challenger R/T came with a Rallye instrument cluster that included a 150 mph (240 km/h) speedometer, an 8,000 rpm
tachometer,[SUP]
[11][/SUP] 1972–1974 tachometer went to 7,000 rpm and an oil pressure gauge. In 1973, the R/T badging was dropped and these models were called "Rallye", although they were never badged as such. The shaker
hood scoop was not available after 1971.
