Haven't done this yet...I'll add it to the list (haven't ever done the task, but from what I understand it shouldn't be too hard).
I don't know too much about the history of the rig. Guy I bought it from installed a Holley Sniper and HEI distributor but judging by the looks of the work they did, they didn't bother to do some things and doubt they did some fundamental work.
