I collected the engine Sunday which is now sat in my garage. It has the mopar electronic distributor so in theory I need the mopar module, ballasted coil, ballast resistor and the little loom to plug it all together. It's available as a package on American ebay for about £100. But I've ordered an updated Gm hei 4 pin module and an e core high output coil for just over £25 for both as i'm tight. There's a company stateside that makes a bracket to bolt the module to the mopar dizzy under the advance can but I'll make my own, again as I'm tight. Apart from cost this setup will give a better spark and is arguably more reliable.
