Thats funny, I never been to this part of moparts and I have owned a 77 macho 440 4x4 for about 9 months now. Its an all original 440 auto with a.c. matching numbers and solid. I've had it for sale for some time now and someone is purchasing it tomorrow. Using the money for my 69 bee or 70 runner. I do however like these trucks very much and will probably look again someday for another. Guess I should have held onto this one being its a 440 macho but the money will come in handy. I wasn't to keen on the 7 mpg deal either lol. Anyone know the production number of 77 macho's with the 440 option? If its super low, maybe I'll change my mind in selling tomorrow haha
