My car has been running great, I drive it all around town and it runs fine all the way through the rpm range( about 5500 to 6000). Problem is when Im on the freeway doing 75+ its making a popping noise through what sounds like the carbs, Im not sure of course because that would be hard to check at 75 mph. Is this a timming issue maybe, Im just not sure where to look first since it runs great at lower speeds. Any thoughts?

It might be a timing issue, but intake popping is normally assoicated with a overly lean mixture. If your spark plug electrodes look whitish, I'd suspect a fuel mixture problem or misadjustment.
Cars that are running lean also commonly do a little sublte surging during normal operation. ------------------ '83 SC |

Yeah, the car use to surge somewhat, I was told by a wrench the there was an air leak somewhere in the carbs that was causing that, after a bottle of techron that problem has since passed. I always wonder about the timing since I do not have a vacume line attached to the distributor. I dont do a lot of freeway driving, but I would just like to fix all the problems none the less.
