When I got my motor going last night the tunning was pretty good for a first start up so I didn't mess with it and took it out to a car show at the local Culvers. She ran real good and the tunning was not that far off. This morning I decided to put the timing light on it to see where I was sitting. It was about 40 degrees advanced. Now my compression is around 11.1 and I have Alum heads and running 93 octane. Quite a few people have told me I am going to have to run retarded so that my engine doesn't ping like crazy. So out of curuoisity I retarded it 10 degres and it runs like crap and kinda ruff. I than bumped it up to about 20 degrees advanced much better but still not as good as it did at 40 degress.
I guess my questions are were they BS me about running retarded? I would think if my quench is good, which I am sure it is because I copied my basic setup from a few others that run the same setup on this board, that it should be ok to run advanced. As for pinging i don't know what to listen for or what it sounds like. How do I tell if I am pinging? Listening to the engine the only sound that is strange to me is that of the valve train because I have never ran a solid cam before. Sounds mean if you ask me! :headbang:
