That 64 Plymouth Fury ragtop is pretty rare as well. How sweet would that be with a Stage III 426 with CrossRam in there!,that is Ivy,s car she and Tony Richards own MopowerMasters,that car is sporting a 440 6 pac,with stealth aluminum heads,here is a pic, also that rambler has a 290,and yes ed they did have a 401 after 1970, however,all there blocks are the same size from a290 ,360,390,401 all used the same engine blocks,there for they are some of the lightest engines for there time,that blue amx is about 4 or 5 tenths of a sec faster than my car!with a 401! yes they run very well, oh btw i know this a challenger site as i own one, but i hope by now everyone knows im not brand loyal, i love all cars which is why i have all these buddies with alot of other muscle cars, we get along great and.................we dont have to compete for parts
