Re: 1954 fouls plugs

Well, one solution is don't leave the choke on as long. I know that sounds like a smart azz answer, but I'm serious.

On my '54, I pull out the choke and crank the engine. At the instant it starts, I push the choke most of the way in. After only a few seconds of run time, I push the choke the remainder of the way in.

With the ultra short distance between the carburetors and the intake port, you really don't need or want a lot of choking.

Don't know what heat range you are running but for older cars I always went at least one heat range hotter that what was called for.

A hotter plug might help. For "around town" and/or city type driving, a one-heat-range hotter plug helps, or an extended tip plug.

Re: 1954 fouls plugs

It would help if you tell us what plugs the owner's manual/AMA specs recommend. I don't know much about the early six-cylinder cars, but recall that the OE AC plug recommendation is heat range 5 or 6, which are on the hot side.

Also tell us the brand/number of the installed plugs. If they are not AC what AC plug do they cross to. Cross reference charts are available on the Web from most manufacturers.

IIRC, it's either AC 44-5 or 45-5. These are the smooth insulator plugs...that use the ribbed boot.

I always had better luck with Autolites in my 54... Can't remember the #

Re: 1954 fouls plugs

I had great luck with Autolite 303's in my 54. Never had good luck with any AC plug..

Not to hijack this thread (much) but what is a 44-5 plug and how is it different from a plain 44 plug?

Expiring minds want to know.....
