ok, to start off, i put a ford racing crate 302 in my 88 speed density mustang, it ran like crap, found out that i had to put a minium of 30lbhr injectors in it and convert it to mass air (both were recomended by the ford racing tech's), so i put a 80mm mass air and 36lbhr injectors in it and did the mass air conversion, runs better but not good.

now it stalls randomly when i come to a stop if i let the RPM's drop too quickly, and when i start it the revs go up and down a few times untill it stalls, unless it rev it out
and it puffs blue when i start it up after it stalls
plus it doesn't feel like it has anymore power that it did stock and it is supposed to have 350hp out of the box

so i changed the plugs, cap, rotor, wires, PCV Valve(cuz it was lettin oil through into the intake)


has anyone else had these problems, or have an idea of what i should do?
