Dont be ashamed about knowing about 6 cyl cars, Australia is the land of straight 6's most cars here were never V8's they were all 6's GM Torana XU1's were triple carb 6 they rallied and race against HOs and beat them, Every family car my dad ever had was a 6, in real terms V8s were kind of rare and special, here in the 60-70's Ford even stopped selling them for a while in the 80's, Gm kept them though.
This car is running an Australian Falcon Bosch distributor, the gap should be 25, but like I said unless the dissy shaft is totally stuffed and flopping around to the point were the they don't open this wont be the issue. I'd still swap them and the condenser, could even be a weak fuel pump, blocked filter etc, or just a poor connection/short somewhere. Only guessing without the car here, wont be a big issue thats for sure. No point stabbing in the dark any further, but it wont be hard to fix.
