Q: Spark Plugs on 1968 – #8 Plug Inaccessible
I have a 1968 400 with A/C and have never been able to contort my arm just right to get the number 8 plug out because of the close quarters to the A/C. I’ve had to take it to a shop to put it on a lift to get at it from below and even then, the mechanics bitch about it. A couple have said they didn’t think it should be that tough and my engine mounts may be off kilter, but they don’t know enough about Firebirds to know for sure. Anyone else have this problem? Anyone have the measurements I need to verify if my engine is sitting in the right place in the bay? Anyone have any tricks to getting at that #8 plug, I’ve tried everything (from top, from below, through the wheel well) and always end up cursing the thing out.
A: I have had the same problem on my 1968/350 with air. I have been able to get it out using a spark plug socket and turning the socket with an open end wrench. I have to do it by laying under the car. My arms usually go numb three of four times during this operation from the cramped quarters and working over my head. It is a major pain to get out.
A: The best plan of attack is to remove the rf wheel and go in through the wheel well.Snap On tools makes a 3/8 drive ratchet in a 1/4 body that works great for stuff like this.I have worn mine out 3 different times from using it so much on the new cars of today. Break the plug loose with a wrench on a short plug socket (they are all not the same) and then use the ratchet to take it out until you can turn the plug with your fingers.
