each engine will like its own timing. Is there an aftermarket cam in it??? Stock or built?? Could idle anywhere between 8*-20* ... to be honest I've gone all over the place with timing all over my years all over my many cars and not have what you are experiencing happen

I dont know much about the car. Dad bought it about 5 years ago, it sat in a garage basically the whole time. I just moved back from florida in novemeber so its my "summer car" for the time being and just trying to get it running right. I want to say it was built to a 408.
