In the foggyness of my brain I recall that one uses either resistor plugs OR resistor wire and not both in older cars. Modern cars with CD spark systems can zap thru all the resistance but not (necessarily) those carz with justa standard coil and breaker point ignition. Many of you >>>LOOK owners have upgraded to a CD system either Mopar or aftermarket for firing your hipo 383 and 440 engines. but Does anyone have some documentation regarding this either but not both thing? Note a 67 Champion catalog shows Resistor plugs (not wires) for 46 and up flathead 6 engines, and 035 plug gap. 42 and earlier non resistor and 025 gap. And no change in the 035 when in 56 the electrics went to 12v. NOW I am running in my 56 277 V8 powerpac engine both resistor plugs AND wires and have done so for 6 years. Wonder if that combo is giving that rough idle??? Conversely in my 41 I am using resistor wires and standard plugs. Since a few of us have 55 and 56 flathead 6 in our semi-finned cars, maybe some more info is needed? Any input appreciated! L. |
