Ok an opinion question for you guys and Pontiac SD guys.
A "friend" has a 62 SD that is hard to start and runs terrible. I told him to stick a set of hot plugs in it as it is a show car and never comes off idle. I have experience with the exact problem as my 62 409/409/ is only driven from the trailer to the show field as it has to be running when passing by the dignitaries showfield entrance tent to judging area. Mine got so bad a couple of years ago I stuck a set of 45 or 46 heat series long reach plugs in it but as many are aware all new plugs are S series plugs that extend the tip a mini amount into the combustion chamber. The 409 runs like a new one and the racing fuel I use has very minimal build up on the plugs when I checked compared to the massive build up on the cold correct spec plugs.
Now, back to the story. The SD owner is in a panic as his car's plugs are also only found with S series AC plugs. He is convinced that the S series plugs will hit the pistons in a SD! The plugs in it are very fouled and are not S AC's.
Opinions?
