best engine swap for '65 rambler american and '63 rambler american
Nash produced some top flight inline sixes in the '50's. Some even came factory stock with dual carburetors. They were no slouch for power. Just never really caught on in the main stream. I know of one now in a Rambler two door that garners a lot of attention when he attends the Nostalgia Drags in the San Joaquin Valley. I'll bet there are some still out there with the recyclers.
