" From: tom jennings <tomj@xxxxxxx> " " Duraspark II is the same as the other one, with the following differences: " " Big "HEI" style cap and rotor " big-cap adapter true for ford, but amc never used them. amc did use the same ign box and trigger. " TFI coil and resistor only later ds2 afaik; earlier ds2 used a high voltage can coil. amc used a conventional points-like coil. " The resistor goes with the coil -- it's square so you have to drill " holes to mount is, so adding the resistor is no big deal. there supposedly is a tfi coil for a particular model ford which has a bracket you can bolt to the engine. tfi coils differ by mounting for every car they came in, even if they're electrically the same. " The "TFI upgrade" and "Duraspark II" are the same thing, basically. nitpicking, i would say that tfi was a subset of ds2. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
