pro-jection or q-jet?

I just recently bought a 78 scout with an AMC 401. The guy that owned it before me put a projection on it in the late eighties. I have been told by a few people that I should dump the projection and put a quadra jet on it. It seems like a good idea to me becasue it doesnt feel like a 401 and runs horrible when it is cold. The projection is a silver analog box with two injectors. Should I go with a q-jet or try and tune the projection? Thanks
