Hi SCSTRANSPORT thanks, I better put a shift kit in it cause I would like for it to last a littel while and have some fun with it.Your engine sounds pretty mean I was thinking about doing something like a double 4 barrel or trying to find one of dose old manifolds that the 390 had in the early sixties that was 3 2 barrel carbs but I would probably have a time to find one.But I am foresure that I am getting some edelbrock heads and ain't decided how to build it yet, but want at least 420 horsepower I heard if you get everything edelbrock I could get that easily but don,t know if that is true.
