1 set. the motor will fit. as I said it's a common swap with little trouble, it may look like it's too close but with the e brake removed, it will fit. the 6 is longer than the V8 by 2 cyls so it will fit length ways with no problem. post some pics, I can only visualize in my head what you might be incountering. the only problem I forsee being a problem is the width, because sometimes the motor needs to be shifted 1" or so over to clear the steering box, but length is not a problem.
