HEI conversion time...

On the far end of the scale, this is what you can get away with. The former owner had a Mopar ECU mounted here on the flat between the heater and wiper motor... I've run this coil now through 2 summers with no ballast, a stock Mopar coil, with no ill effects. On a simple, mild, low compression street engine I see no reason for the fancy, expensive, E core and other "big" coils.
i love seeing how less than optimal these things can be mounted :smile:

well i got everything hooked up and it fired right up, even got lucky on the distributor wires ;) i unwraped about half the engine wiring to remove the wires that got abandoned and got most of it cut clear before i had to go to work today. looks like the OEM coil was starting to weep a little. glad i changed it out too. with the plugs regapped to 45 it's runnin' just fine.
just need to rewrap the wiring and mount the relay so it's not flopping around in there.
as this is my daily driver, it's nice having something easy to work on with parts available pretty much anywhere
