HEI conversion benefits

Yes id buy a mid price one where the manufacturer is happy to put their name on the box
or preferably on the module

wells neidorff borgwarner delco Napa Echlin etc

i would not buy a HIGH POWER version from any of the ignition specialists. there isn't really a lot they can do to make it any better than any other apart from some blue printing to their own specific coil.

i chunter on a bit about HEI here
FBO's black HEI ignition box


this is what i put in the ebay search box when looking for a module in the US

(ac delco,wells,petronix,car quest,napa, niehoff,borg warner,gm,mallory,jegs,moroso) (dm 1906,d1906,acc35361,acc35367,d2000,21040,ech tp45, dr400 ,cbe4,cbe22,10482820,607,555-40600,97857) (module,hei)

But i currently have one off a peugeot or fiat

hella 5da006623051

and a run this 1976 chevy truck coil

1976 CHEVROLET C20 PICKUP 4.8L 292cid L6 Ignition Coil | RockAuto

of look for

Standard Motor Products DR35 Ignition Coil

i have more money in a distributor recurve than i do in module and coil...

I also run a diode to protect my meagre investment

more about that here

New release Distributor for Slant 6

the diode + postage cost more than the coil :)

I added horrible document in my post earlier this is an easier read and you can download it
its by the same Dr Holden but its a bit more real world rather than science paper
