Some Sparkplug GAP direction

Dear All,

It's time to change out the plugs in my 40 Ford Coupe. A year or so ago I took it to a local performance shop to help sort out some problems. The upshot of it was besides setting things to what they thought should be the case the shop installed new plugs.

Here is where I am at: The spark plugs installed are Champion RJ14YC with a gap of .045. I was thinking this might be a bit too wide, but I really do not know. The tune up shop said they like to install the coldest range of plugs that will not fowl. This seems to be the case as they looked OK and the car has been running fine. But as the car is not driven other than weekends I decided to change them out.

The specs on the engine are as follows, many details are sketchy as I did buy the car and not build it myself.

Engine: 1965 327 (now 332)
Heads: Old style power pack with the single triangle marking
Manifold: Edelbrock C-3BX
Carb: Edelbrock 1405 600 CFM
Cam: ? reported to be an Edelbrock Performer
Ignition: Pertronix Electronic with vacuum advance (I put this in)
Timing: 10-12 degrees advance
Idle: 750 RPM

The car does run well after it warms up (no choke!) I am just doing some regular maintenance.

So does the plug style seem correct and what about that GAP?

Thanks to any and all of you in helping this newbie stay on the street.

Sincerely yours,
MrPhat40

Seems to me back in the day, that we ran J-12Ys,so a 14 is hotter. .045 is normal for an elec ign on a chev.You want the widest gap that doesnt misfire.

If the Pertronix unit is not an amplified system, a smaller gap (.035" or so) might be appropriate.

Plugs

Al

The plugs you are running are the same as the ones I ran in my 327 ,if they did not fowl when you were running,and looked fine when you took them out, I would not change to another plug . I ran 45 thousand gap also .
