Personally I like HEI and Ive even used a cheap Ching chong one that I just swapped out the module for a proper Bosch one and coil on my Cuda. Yes full 12 volts , yes open up the gap, they're normally over .060 . But as Jim and Tubman said Its really not a big requirement on a low compression flathead. Im just running a Speedway electronic one thats been in for 7 years now , daily driving .
