Re: IML: More on Plugs for '56

[Christopher Hoffman <imperial67@xxxxxxxxxxxxx>]

Jay,

I'd avoid platinum in an older Mopar (like, pre-2000). Tried 'em once in one
of my 1990s Jeeps (with a 318, er, 5.2) and the car barely idled. Went back
to regular Autolites and all was well. Heard the same from several other
people.

As for SplitFires, in a desperate attempt to pass CA smog test after my '67
had sat for close to a year without a long drive (though the new paint
looked great!), I tried the snake-oil approach, including SplitFires, and
while the car ran well for about 100 miles (and passed smog), it then began
to misfire terribly. Upon removing the SplitFires, I found that three of
them had completely blown off their electrodes (all three per plug) and the
rest were looking mighty ill. That was when I discovered Autolites for the
first time, and I never went back.

A properly set-up 440 with a stock distributor and the timing set perhaps a
little more retarded than spec (as little as 4 deg BTDC rather than 16)
should run quite well unless there is some other problem requiring more than
a band-aid solution.

Just my $0.02!
