Spark Plug in #7?
 

Ok ... I've changed a few spark plugs in my day but I can't get the ___ plug started in #7 on my 63/68 engine 400. It's under the steering shaft and it's a two finger job at the best. I have ground reliefs on the 13/16 th's short sockets that have and can't get the socket over a finger tight plug or get the plug started when it's in the socket! I have always worked on SBC's and Olds engines so this is my 1st go at a Pontiac. Is there something about Pontiac tool/head (#15) clearance? John

Is the exhaust gasket protuding any? had one that was a bit fat & socket hit it.

An old trick from an old mech. friend that has worked for me,, slip a short lenght of gas line or a small rubber hose over the end of the spark plug to help it get started, works for me on those tight plug holes. Hope this helps.

I had the same problem with my Lemans. I pried up on the steering shaft with a crow bar--just enough to slip the socket over the plug-not enough to bend the shaft. Then insert an extension in the socket and tighten. Pry up on the shaft to remove the socket. Hope this helps.
