" From: Tom Jennings <tomj@xxxxxxx> " " " I don't want to use knock sensors, crank-position sensors, " multi-coil or HEI ignition. I know all those things make for a " better system, but I don't have the time, money nor inclination. " " [] " " " " *** All-GM OEM parts are the way to go. Cheap reliable and " plentiful! aren't these two statements somewhat at odds? and swapping in a hei dist is easy, compared to everything else you're doing. i don't believe the chevy six ever had tbi, but if the ecm wants dist inputs wouldn't it be easier to mix 'n match gm parts than adapt to the duraspark? count me in your audience for any writeup! ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
