Thanks JWL, was wondering what kinds of plugs you are using also, I got mine from Kanter, ended up being Y18's (Champion), I suppose the H10's are long obsolete. They (Y18's) are a bit "taller", the electrodes add about 3/8" onto the threaded length, I suppose this is no issue at all. Never been a fan of Champions, yours look like AUTOLITE?
Noticed also that you have the linkages off from the carb, probably to facilitate getting at the distributor for the tune up...I am assuming.
Most of all thanks for the response, it is nice to see someone actually is active in this discussion yet !!!

I believe they were Champion J-18Y. I changed the silver color of the plugs to black to more resemble what the plugs looked like back in '55. Packard changed cylinder head design somewhere along the line. They went from a machined combustion chamber to cast finished and went to a longer reach spark plug. You do not want to put the shorter reach plugs in the newer heads nor do you want to put the longer reach plugs in the older heads. Someone here with more recent and relevant experience will clarify what I just wrote.

Good Catch on the missing throttle linkage. I had removed the carb and manifold and needed to finish connecting things.
