My 1980 has a high altitude distributor on it. What's different about this distributor that makes it a high altitude?

You'll have to admit, that was funny!king80vette said:If you don't have any usefully information don't say ANYTHING!!!:eyerole
The 80 doesn't have an ECM. The computer controlled carb was only on the 81.pgtr said:Steve, I can't offer any specific solutions as I'm not familiar with your specific model. But I've found GMs of the early 80s with age and miles on them to be problematic at times with respect to things like a decent idle. In some cases I've traced this to early electronic (or computer?) emissions controls combined with old school carb and ignition. E.g. electronic controls on carbs and O2 sensors electronically controlled distributor advance and what not... just some possible ideas to consider...
Have you checked all the basics? Here are a few thoughts. I have no idea what your level of expertise so don't be offended if they are things you have already looked at.king80vette said:Thanks for the information and I’m sorry for the remark above. It’s just that I’m getting frustrated with this car. I’ve been working on it for 3 1/2 years. Two weeks ago it received top flight from the NCRS and I’m happy about that.
But the problem is it just will not idle well. Now I’m not asking for perfect idling just decent. The distributor does have the part number you mentioned. I can’t get the timing set. As I get closer to the correct setting the engine runs worse. So I set it where it runs the best. I’ve turned the idle mixture screws in and out so many times I think I’m going to ware out the threads. Was the high altitude distributor listed as an option on the build sheet or order form? I have both of these documents. The car was delivered to Pennsylvania in 1980 and has always been in Pa. Is there a way I can check to see if it was recurved? Maybe someone replaced the original distributor with this one. Is there a way to check if the carburetor is jetted properly? It seams to be running lean because the spark plug insulators have a red look to them.
Any help with this issue is appreciated and again sorry for the bad attitude.
