Brian Moore Now I am a big fan of updates and if you like original that is fine. If you go to HEI you'll save yourself a lot of misery with related problems plus you'll get powerful ignition. Also you can modify an early HEI (not computer controlled) right at home probably with tools you have 4 inch grinder,drill,hacksaw,file. I find a clean used donor distributor at the junkyard,make it same dimensions as the one that is in there.Good Luck !!
