I know for a fact (because I have seen them) that you could get a 340 barracuda (BH vin) in 72-74. I have not seen any 70/71's this way and I do not believe they made any. I think the 340 in 70/71 was only available on cuda's (BS vin) unlike the Challenger where in 1970 you could not get an R/T Challenger with a 340 (340 Challengers in 70 were regular challengers with a 340 performance package).
