Back in around 1978 I bought everything I could for a 1970-71 440 Six Pack. I owned two A12 69 Runners then and nothing was available for that motor around that time. I got this for a 1970 motor from the Dealership I use to spend most of my paycheck at. Crank, Rods, Piston, Rockers, Cam Shaft lifters, timing chain and lots of small parts. Bearings I bought at the local speed shop. I also bought rocker shafts but do not remember is they were Six Pack specific from the dealer. All this was still available at the Dealer. Built the motor myself and decided to sell it to a guy that had a 1970 440-6 Cuda. He finally only wanted the short block. I took the intake carbs, cam lifters, rockers, heads and valve cover off the motor and still have all that. I always thought the Six Pack Lifters were still available in places maybe not the dealership. I guess I have a lot of Scrap metal the way people have posted but I will like build another motor and put it in my Challenger Convertible.
