I've been thinking about this a bit more today and the cam may need some more advance. I have some time this week and was thinking about giving it a try.
The vacuum on this engine has always been low, I don't think I've ever been able to get it over 10" idling in park. It is lazy off the line and seems that way pretty much all around.
Any ideas what I should expect from this combo in regards to idle vacuum? I would think it should be at least 12 to 15" at idle in park.
It also seems odd that it'll take up to 36 degrees of timing at idle with no kicking back. I wouldn't think that it'd want any more than 20 degrees max.
