" From: JOE FULTON <piper_pa20@xxxxxxxxxxx> " " IMHO those Chevy guys don't know what they are talking " about. 1975 was the first year GM used the HEI in " Chevy sedans. That particular year of distributor had " balance weight bushings which wore out quickly and " affected timing. Also, some of the early modules were " affected by heat I think. GM quickly remedied those " ills and the HEI has an excellent reputation. 40,000 " to 45,000 volts really makes a difference in the " ability to fire a spark plug. " " And why else would a company like DUI adopt that " design for an aftermarket line of distributors? i agree completely. i've also heard to avoid the '75 hei. my '68 199 has some tens of thousands of uneventful miles on its hei. this was salvaged from a junkyard and 'reconditioned' by soaking overnight in marvel mystery oil. ________________________________________________________________________ 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://www.amc-list.com/mailman/listinfo/amc-list
