I had the engine rebuilt. The shop degrees cams as part of the basic rebuild. They told me they did. So, supposedly they did but lack of power on the mountain passes made me wonder and I let Scott know that it might be something to check when he got the motor.
Without fully understanding the nuances of GM EFI timing, from a carburetor, duraspark, AMC 360 standpoint, I haven't had much luck with an AMC motor idling at 0 degrees actual timing (no vacuum advance). We usually set them around 16 actual (no vacuum advance, but with mechanical advance) to get a decent idle.
Eagerly watching this and other threads because I'll be neck deep in this soon. Learning as fast as I can.
