HEI conversion time...

so the ignition module in my 74' swinger is starting to die. car is bone stock 318 w' aound 70,000mi. the module, (OEM one bled out a while ago), is a replacment that i had salvaged from my deceased motorhome. it's gone from missing at a 2500 rpm after driving it for 15 or 20 min to also having a low rpm miss all the time. i considered just throwing a new Standard BlueStreak at it, but that's just too simple...and no fun :D
