I would find a decent cam not to big... not bigger than a .480 lift.... unless it has alot of miles. Go with a .450 to a .460. To go along with that cam a set of lifters, timing chain, and a gasket set. The q-jet will work aslong at it would bolt to the intake. No biggie and timing borrow a timing light and just play with it until you find a happy medium. check it, change it, and drive it until you find it.
