Re: [Amc-list] Timing cover, dist.

[Matt Haas <mhaas@xxxxxxx>]

Mid 12's probably isn't fast enough for point bounce to make much 
difference. Also, if I'm not mistaken, the points are just acting as a 
trigger for the MSD box which means you're not passing much current 
through them. Hot Rod or Car Craft did a distributor shootout in recent 
years and I think they were slightly over 5,000 RPM when point bounce 
became an issue with a heavy duty point set.

The big advantages electronic ignition has over points are reduced 
maintenance (helps keep emissions in check), ability to handle more 
current (more spark = more complete combustion, again helping with 
emissions), and more stable timing (well maintained points do a decent 
job of this but most people don't maintain their cars well which results 
in increased emissions). When I put a Pertronix Igniter on my 68 
American, I noticed no difference in fuel economy or performance but the 
car does start easier and has much better cold drivability with no other 
changes.
