Not hard , but a 74 is not that powerful, maybe no more hp than the old 326? unless you build it at the same time....I have a 72 400 in mine , but w improved heads etc... engine wise its a direct swap, motor mounts etc fits...right Q? You`ll prob. get a few more insights from others....
and if you go to "ramblings and chatter" there`s a post "hp for a wm 2bbl 350? " that might give you some ideas, or who the people are w ideas...
