" There is no DESIGN difference in Duraspark I and II. At best, II had a
" heftier transistor to drive the coil, but semiconductor technology has
" improved so much since the 1970's that I wouldn't (and haven't) given it a
" second thought.

interesting.  i don't know about the tfi coil, but the ds1 coil had
lower primary resistance than the early ds2 coil.  there are other
variables like dwell though.

" The HEI module is basically a duraspark box capable of driving a BIG coil.
" It's sort of "80's" tech where the duraspark is "70's".

except that hei came out in '75 and carried through the '80s
essentially unchanged...

" So, will the extra 258 HEI I have drop into the 67 232 (with the

" better so I can take some trips this Summer... maybe even do Cordova!

i can tell you for a fact my '68 199 is running one.  it could stand
to be recurved, but it's run flawlessly otherwise, even before i
bypassed the resistance wire.
