I just replaced my plugs on my 289, yeah it is a bit of a pain to do. But I found a neat little trick that might help someone. On the #3 cylinder I think only a normal 5/8 1/2 inch drive socket would fit but the end of the plug stuck out a little. So I took a crappy 1/2 in extention and drilled a fairly large hole in the end for the plug to slip into and it worked very well! You just have to drill a big enough hole b/c the plug goes in kinda slanted. Well there ya go hope that helps!

If it is an original 289 head it is supposed to have a 13/16 spark plug......isn't it?

Since when is it hard to change the plugs on a 289? You think that's tough, try a 67-70 big block Stang.

I have found the back one on the passenger side a bit challenging, but doable.

Urban Myth?

Isn't there one particular flavor of Big Block that requires the loosening of motormounts and a floor jack to get to the 2, 3 and 5, 6 plugs?

Or is that urban myth, like the hook handed escaped lunatic that kills kids who park and smooch on the backroads?

The best aid you can have when doing plugs in an old Mustang is a spark plug socket with the hex portion on the rear.....it allows you to turn the socket with a 3/4" wrench when in those tight spots.

supposedly the Boss 429 had to have the motor mounts loosened up to change plugs.

I can change the plugs on my car but it is very difficult, time consuming and a good yoga workout.

I think that was a myth, started by some big block Stang owners that avoided hard labor. My 67 with the 390 and later the 427 was difficult, but not impossible. Just took patience. Of course, mine didn't have a power brake booster to complicate things either. RonStang is dead right with the hex headed spark plug socket, they're a life saver sometimes in tight spots.

The spark plug soket was too long, it hit the header and wouldnt engague the plug thus having to use a shallow socket and the drilled extention.
