    new plugs and wires for my 72 Eldorado...need advice.

    What plugs/wires should I get for my 1972 Eldorado? I don't know anything about different quality/brands of these so any suggestions would be great. I keep hearing Delco but I believe thats in reference to newer caddys. Any help is appreciated. Thanks!

    I just went to ac delcos website and you can still buy quite a few parts
    including ignition parts(plugs/wires/cap/rotor etc
    for your cadillac
    here is a link to their website
    http://www.acdelco.com/html/catalog/index.htm

    I hope this helps
    oh also try autozone here is a link to their site

    ok well i just bought some ac delco plugs. i took a plug out of my engine and they look GREAT, just the very light brown kinda "dusty" look that means everything is OK. There was hardly any wear to them at all. My question is, should I replace them all anyway? The previous owner who had the car said they didn't do anything for 4 years, so i assume they are at least that old. Time for new ones or let it go for a while?

    Also, should I replace the wires? They were out of stock at autozone so I'd have to wait for a while if I do, but the wires appear to be in good condition from the outside, and everything is running fine.

    Well If the engine is running smooth and there is no interfearence when the radio is on (you know that noise that can sometimes happen)
    well heck keep them , but plug wires can loose their strength over time
    but if them are not brittle keep'em
    i once had a 1961 chevy impala with a 283 v-8 with 90k original miles
    and that car ran perfectly smooth and the plug wires on that car were at the time 35 years old and no noise through the old am radio at all:coolgleam
    so if ther look,feel, work good heck keep'em
    but the plugs are a little old you say?
    plugs are cheap so change em but if you think they look good keep'em!

    one more thing have you concidered switching to electronic ignition?
    they are a lot more reliable than the old breaker point system on your cad.
    if you want to upgrade or for more info go to the link i have listed below
    http://www.pertronix.com/new_product...ss/ig_pg21.htm

    this is some of what they say about the upgrade
    PerTronix offers Ignitor electronic ignition conversion kits for most GM Delco points-type distributors 1958 to 1974. Part number 1181 also fits the more widely found single point 1958-74 applications.

    The Ignitor module replaces the stock points and condenser using a Hall Effect integrated circuit to control dwell accuracy to within 1/4?. No “black box” is required as the Ignitor fits entirely under the distributor cap and delivers twice the voltage to the spark plugs, according to PerTronix. Used as a timing trigger, the Ignitor is compatible with most capacitive discharge systems including MSD and Pertronix’s Second Strike ignition. Additional kits are available for most points-type OEM and aftermarket distributors.

    PerTronix helps the enthusiast complete their ignition upgrade with 40,000 volt Flame-Thrower®coils and high performance low resistance Flame-Thrower® ignition wire sets featuring dual current path.

    i hope this info helps you keep that big old eldo running for a long time
    (i wish i had one)
