GM-HEI Modules

[peter paul fenske]

Hi 

I have done this swap a few times since the large cap
HEI is better for arc cross over with no ill effects

In fact the corvette stuck with this till 91

The small cap dist is regarded as unreliable

of course someone will like the external coil feature
but this is just something extra to mount
