Can you get to all 8 plugs on a 91 rs with a 305 from up top?

 

If your car has all the SMOG equipment still on it getting them all from the top would be very difficult. On my TPI engine with SMOG I remember having to get some from the bottom and most from the top but it depends how deep your tool box is...if you ditch the SMOG stuff they are all easily accessible from the top.

 

I would just plan on getting the back 2 on the passenger side from the bottom. It is just easier in the long run in my opinion.

 

I couldn't, but maybe you can. As above though, don't bother; go under the car to reach at least the back 2 on the pass side and save yourself some grief.
