Ah, right! It's the exhaust valve on #8 then!

Sounds like a cam lobe going flat, usually the exhaust letting the burned fuel back fire thru the carb. Pull the left cover and investigate.

And there you have it.
Winter projects are always fun, but expensive. Start putting away some funds now so you can just dig in and keep working on it.

Sticking valve stem??? A friend recently bought a 396 car that had been sitting a long time. It would intermittently idle rough and pop thru the carb. He gave it a dose of Sea Foam or some similar product and drove it. It smoothed out and now runs fine. Just a thought....

I've had 2 cars with sticking exhaust valves in recent years. The clearance from guide to stem was just too tight especially when the motor got some solid heat in it. The first was the 427 in my Dad's car, the second was a customers 327. While wiping out a cam lobe is not rare, please don't short cut the process without making sure the rest of the valvetrain is up to snuff.

I know it's expensive and frustrating..........but so is doing it twice.
