383 engine noise question

Thanks for this thread. I think it will be very helpful to others. My thoughts are that the cam went flat. Since you say it's missing, and tapping. What happens when you pull plug wires one at a time? Might be time to pull the intake to look at the cam.

When I changed the lifters all the bottoms had normal wear and still looked like they should. My understanding is if the bottoms of the lifters look normal the lobes should be ok. Missing and light knocking happens at = or >2000rpm.

I took a day off work to check the valve springs and do the dead cylinder test. No broken springs. When I pulled the plug wire on #2 cylinder, which is where the noise is at, the light knocking went away. Not good $$. :-( I have been talking to the people who rebuilt the engine 5 years ago. I have to call them back to talk to the owner tomorrow and see what happens. Not sure if they will offer anything worth while. Other wise I'll have to find some place close to home to take it since it sounds like a pull the engine to fix it. There is a place near that buys/sells classic cars, does mechanical work and body work. They show three babes with grease on under the service tab. If they work on your car I want to watch. :-)

For anyone's curiosity here's the link to the place http://baltria.com/home/
