Default Curious rough idle

I drove the 68 to wrok as it was nice (14 miles each way) Now on Coronado Island the bridge is the only way on or off unless you go 30 miles out of your way to the Silver Strand exiting damn near at the Mexican border. Anyway there was a bad acident on the bridge and traffic was backed up 4 miles. So in dead locked traffic she went from a nice steady 750rpm idle to a lumpy 400-600 idle and several times I had to put her into nuetral and rev a little so she didn't stall. Never once did the temps go over 175 so good there. As soon as the wreck was cleared and was on the freeway it was fine. Stopped at several intersections and purred like a kitten. This has happended before she does not like sitting idling more than 10 minutes

Vapor lock??
Any ideas??

A little more than mild. Heads are matching # 11/1 compression with torqer 1 intake and Eldebrock 600 model 1400 carb/ pertronix II ignition.

Cali,

This may be a good question for Lars. He's the igintion/carb guru and this sounds like ignition/carb to me.

Agreed. It may be too big of a cam for extended idle periods.
