I have a couple of projects I work on for fun. I'm not a pro and learn as I go.
I've got a 440 I've been reviving that was stashed in a garage for 27 years and have been having decent success replaced the tank and fuel lines, sorting out the cooling system and I've put disk brakes all around. The 440 is original to the car and I was careful starting it since it had been down for so long. It runs and I'm working out a few other loose ends now. The previous owner has passed away and I don't have a solid source of information anymore, but according to him the car had been bored out 60 over and has some sort of purple cam in it.
I've recently learned that the current carb is a 600cfm Holley, and a local carb shop set me up with a rebuilt 750cfm. Before I took it home, he demonstrated it on an engine on a stand that he uses for that. Now as look at swapping it in, I see that it doesn't have a connection for the distributor's vacuum advance line. There's a port there, but not the tube I would expect. The hole is not threaded.
I asked the carb shop about that, and they suggested I use different springs in the distributor and just forego the vacuum, especially since this car has an aftermarket cam. Can anyone recommend where to start with this? I haven't done anything with springs on a distributor before.
I already have a Davis Unified distributor waiting to go in, but I'm expecting any info that would apply to springs for a stock distributor might hold true for that.
Any suggestions on where to start?
