    Was a 318 motor available in the 1970 dodge challenger R/T convertible? And if so how can I tell if the car is a true R/T?

    I cannot find anything saying the 318 was available in a 1970 Challenger R/T, convertible or hardtop. The base engine was the 383 and the optional engines were the 375hp 4-barrel 440, the 390hp three-two-barrelled 440, and the 426 Hemi. I know you should never say the factory never produced a particular car but I would have to have all kinds of paperwork to prove a '70 Challenger R/T with a 318 was a legit factory car.

    383 HP was base engine in 70 RT Challengers, with 440-4 BBL, 4406Pac and 426 Hemi being options, no 318 or even 340 RTs, Challenger vin starts with a J , second letter would be S if its an RT so vin would be JS23 for coupe JS27 for converts and JS29 for RT-SE coupe , fifth digit is engine code 383 HP is N ,440 4BBL is U ,440-6BBL is V and Hemi is R, sixth digit is 0 for year 0 being 1970 , seventh digit is manufacturing plant such E or others. in 1971 the 340 became the base RT engine.non RT vin starts JH---

    Absolutely, positively NO 318 R/T Challengers, period, dot. That, you can take to the bank. The R/T was the performance version of the Challenger, not the pedestrian version. The engine possibilities are stated above.
