Maby, but it dosen't seem like they used 305's in cop cars, maby they did. For a shure test of the PI ( Police Interceptor ) engine your getting, b4 you take the car apart, take it for a spin and see how it performes. If it is a 350, it should have duel exzaust, if it dosn't, that's not a dead givaway it's a 305 as they don't put duels on all 350's, but if it does have a stock duel exzaust, dead givaway it's got a 350. Look at the 1989 PDF to see if it has a diffrent number. I would check but I don't have Adobe reader right now, I have to find my disc.
